Your dishwasher just stopped mid-cycle and flashing a code you have never seen. Every brand uses its own code system – and a code that means one thing on a Samsung means something completely different on a Bosch. This guide covers the most common error codes for the brands Halifax homeowners have most often, what each one actually means, and which ones you can clear yourself without a service call. For Halifax specifically, there are a few code patterns that show up more often here than elsewhere because of Atlantic salt air and the city’s water quality – we cover those too.

How dishwasher error codes work

Modern dishwashers have a control board that continuously monitors sensors: water level, temperature, motor speed, door latch status, and drain flow. When a sensor reading falls outside its expected range – or a component fails to respond to a command – the control board logs a fault code and typically halts the cycle. The code is displayed on the front panel, sometimes as letters and numbers (E1, LC, F8E4), sometimes as blinking light sequences on older machines without a digital display.

Most error codes fall into four categories: water intake problems (not filling fast enough or too much water coming in), drain problems (water not leaving the tub after a cycle), heating faults (water not reaching the right temperature), and door/latch faults. A fifth category covers control board communication errors, which are less common but more expensive to fix.

💡 Did you know: You can often clear a dishwasher error code by power-cycling the machine – turn it off at the control panel, wait 60 seconds, then turn it back on. This does not fix the underlying cause, but it tells you whether the fault is persistent or a one-time sensor glitch. If the code returns within the next cycle, the problem needs investigation.

Samsung dishwasher error codes

Samsung dishwashers are common in Halifax HRM – they showed up heavily in the Clayton Park, Hammonds Plains, and Bedford new-build waves of the early 2010s and are now starting to show age-related faults. Here are the most frequently seen codes:

LC or LE (Leak Detected) – The most alarming-looking code, but often a false alarm. Samsung uses a moisture sensor in the base pan. If condensation or a tiny drip reaches the base, the sensor trips and shuts down the machine. First step: turn off the water supply to the dishwasher and tilt the machine slightly forward to drain any water from the base pan. If the pan just has minor condensation and no active leak, the code clears after the base dries. If the pan has standing water, look for a leaking door gasket, damaged spray arm, or cracked tub – those need a technician.

4C or 4E (Water Supply Error) – The dishwasher is not getting water, or not getting it fast enough. Check that the inlet valve is open and the supply hose is not kinked. If those look fine, the inlet valve itself may be faulty – a $40 to $80 part that a competent DIYer can replace. In Halifax homes on private wells, this code occasionally appears when well pressure is low in dry summer months.

5C or 5E (Drain Error) – Water is not draining out of the tub. The most common cause is a blocked filter or a kinked drain hose. Remove the lower rack, pull out the cylindrical filter at the bottom of the tub, and rinse it under running water. Check that the drain hose behind the machine forms a high loop before it connects to the sink drain or garbage disposal – a missing high loop allows backflow that triggers this code.

HE or HE1 (Heating Error) – The water is not heating to the target temperature. Can mean a failed heating element (common after 7 to 10 years), a failed thermistor, or a wiring fault. The thermistor is a $15 to $25 part; the heating element runs $40 to $70. Both are DIY-replaceable on Samsung models, though they require removing the lower spray arm and the tub bottom.

OC or 0C (Overflow Error) – The tub has detected too much water. Usually caused by a faulty water inlet valve that is not closing properly, allowing water to keep entering. Turn off water supply immediately if you see this code. The inlet valve replacement is the typical fix.

LG dishwasher error codes

LG dishwashers in Halifax are common in newer constructions and renovations from 2015 onward. LG uses a straightforward alphanumeric system:

IE (Inlet Error) – Water inlet problem. Same as Samsung’s 4C – check the inlet valve and supply. LG machines are particularly sensitive to supply pressure below 20 PSI; homes with aging water pressure regulators in older Halifax neighbourhoods like the South End or Hydrostone sometimes trigger this code after the regulator degrades.

OE (Outlet/Drain Error) – Drain problem. Clean the filter, check the drain hose for kinks, confirm the high loop is in place. On LG machines, also check that the air gap (if your Halifax home has one installed at the sink) is not clogged. Air gaps need to be cleaned every year or two.

HE (Heater Error) – Same as Samsung’s HE – heating element or thermistor fault. LG heating elements tend to fail slightly earlier than Samsung’s in salt air environments, based on what we see in Halifax service calls.

tE (Thermistor Error) – The temperature sensor has failed or is reading out of range. Often clears on power cycle if it was a transient reading. If it returns, the thermistor replacement is typically a sub-$30 repair.

LE (Motor Error) – The wash motor is overloaded or has stalled. Can be caused by a piece of broken glass or a utensil that has fallen into the motor area below the filter. Remove all racks, pull the filter assembly, and visually inspect the sump area for debris. If the motor itself has failed, repair costs run $180 to $280 and at that price, weigh it against the age of the machine.

Whirlpool and Bosch error codes

Whirlpool (which includes Maytag, Amana, and KitchenAid) uses a different format. Older Whirlpool models use light-blink sequences rather than digital codes; newer ones display F codes followed by E codes:

F8E4 (Flow Meter Fault) – The flow meter measuring how much water enters the tub is failing or has debris blocking it. Often clears after a filter clean and power cycle. If it persists, the flow meter is a $25 to $50 part.

F3E1 (Thermistor Fault) – Temperature sensor issue. Replace the thermistor, which sits near the heating element at the tub bottom.

F2E2 (User Interface Fault) – Control panel communication error. Try power-cycling. If it persists, the control board or touchpad assembly needs replacement – typically $80 to $180 in parts.

Bosch is different from every other brand in that it uses a predominantly number-based system and hides some codes in a diagnostic mode. The most common Halifax Bosch codes:

E15 (Flood Protection / Anti-Flood Sensor) – Bosch’s equivalent of Samsung’s LC code. Water has reached the base pan flood sensor. Tip the machine slightly forward to drain the pan. If it keeps happening, look for the source of the water getting into the base.

E24 or E25 (Drain Fault) – Drain is blocked or the pump is not running. Clean the filter and pump cover (Bosch has a separate pump cover that needs to be removed and cleaned – it sits next to the filter in the sump). This is the most common Bosch code in Halifax service calls.

E09 (Heating Fault) – Heating element circuit fault. Bosch heating elements are integrated into the circulation pump assembly on newer models, making this a more involved repair than on Samsung or LG.

The Halifax salt air and hard water factor

Halifax’s combination of salt air and variable water quality affects dishwashers in specific ways that you will not find in inland Canadian city guides. The salt air accelerates corrosion on any metal component near the dishwasher’s exterior venting and around the door gasket area. Gaskets on Halifax dishwashers typically start showing salt-air cracking at 7 to 10 years, whereas the same machine in Winnipeg might last 12 to 15 years without gasket issues. A cracked gasket causes the LC/LE (leak detected) codes on Samsung and Bosch respectively.

Water hardness in Halifax varies significantly: municipal Halifax Water supply typically runs 60 to 100 mg/L (relatively soft by Canadian standards), but homes on private wells in Hammonds Plains, Sackville, and Fall River often have water in the 150 to 250 mg/L range. Hard water causes scale buildup on spray arm nozzles (triggering poor wash performance before any error code appears), on the heating element (causing HE codes), and in the filter mesh (causing drain codes). If you are on well water and seeing recurring error codes, a whole-home water softener is worth the investment.

⚠ Red flag: If your dishwasher shows an E15 or LC code (flood sensor / leak detected) and you can see water visibly under the machine on your kitchen floor, do not restart it. Turn off the water supply at the shut-off valve under the sink and call for service. Running the machine with an active base pan leak risks water damage to your subfloor and cabinets.

What you can fix yourself vs. when to call a tech

These are worth trying yourself first, in order:

  • Power cycle the machine – turn off, wait 60 seconds, restart. Clears transient sensor glitches on all brands.
  • Clean the filter – pull out the cylindrical filter and flat mesh screen at the bottom of the tub, rinse under running water. Required maintenance every 2 to 4 weeks for heavy-use households. Fixes most drain codes and some circulation codes.
  • Check the drain hose high loop – the drain hose should loop up to cabinet height before connecting to the sink drain. No high loop = backflow = drain codes.
  • Inspect for visible leaks at the door gasket – run your hand along the door seal while the machine is running (carefully). A leaking gasket is visible and replaceable as a DIY project – gaskets run $30 to $70 depending on model.
  • Drain the base pan (for LC/E15 codes) – tilt machine slightly forward to drain any accumulated water, then check for the source of water getting into the base.

Call a technician when: the error code returns after multiple power cycles, the motor or control board codes appear (LE, F2E2), you see active water under the machine, or the heating element codes persist after a filter clean.

Frequently asked questions

How do I clear a dishwasher error code?+

The first step for clearing any dishwasher error code is a power cycle: press the power button or turn the machine off at the control panel, wait at least 60 seconds, and restart. If the code was caused by a transient sensor reading – a voltage spike during a storm, a brief low water pressure moment, or condensation that quickly evaporated – the power cycle will clear it and the machine will run normally. If the code returns during or after the next cycle, you have a persistent fault. At that point, address the specific code – clean the filter for drain codes, check the inlet supply for water errors, and inspect the gasket for leak codes. If those steps do not resolve it, a diagnostic service call is the next step.

Why does my Samsung dishwasher keep showing the LC code?+

Samsung’s LC code (sometimes shown as LE) means the flood sensor in the base pan has detected moisture. A one-time LC code often clears after tilting the machine slightly forward to drain any condensation from the base. If the code keeps coming back, there is an active source of water getting into the base – the most common causes on Halifax machines are a cracked or hardened door gasket (accelerated by salt air exposure), a failed door latch that allows spray to escape during the wash cycle, a dripping water inlet valve, or a damaged spray arm that is hitting the tub wall. Each of these causes a small amount of water to accumulate in the base pan over repeated cycles until the sensor trips. Have a technician identify which component is leaking rather than just clearing the code repeatedly.

What does the E24 error on a Bosch dishwasher mean?+

E24 on a Bosch dishwasher is a drain fault – the machine is failing to pump water out of the tub at the end of a cycle. E25 is a related code indicating the drain pump impeller is blocked. For both codes, start by cleaning the filter and the separate pump cover that sits next to the filter in the Bosch sump area – Bosch has a twist-off cover that many owners do not realize exists and never clean. Behind it, check for food debris, glass fragments, or a piece of plastic that has fallen in and blocked the impeller. If the drain path is clear and the code persists, the drain pump motor itself may have failed, which is a $80 to $150 part replacement. Bosch dishwasher E24/E25 is the most common error code we see in Halifax service calls by a significant margin.

Is it worth repairing a dishwasher that keeps showing error codes?+

It depends on the age of the machine and what the codes are pointing to. For a dishwasher under 8 years old, most individual component repairs – heating element, thermistor, inlet valve, drain pump, door gasket – are worth doing because the machine still has 5 to 10 years of useful life. For machines 10 to 12 years old showing repeated error codes from different systems, you are often looking at end-of-life component fatigue across the board rather than one fixable problem. A good rule of thumb: if the repair estimate is more than 50 percent of the cost of a new comparable machine, and the dishwasher is over 10 years old, replacement often makes more financial sense. Get a diagnostic quote first – a tech can tell you within the first visit whether you are looking at a single fixable fault or a broader age-related decline.

Do Halifax’s water conditions affect dishwasher reliability?+

Yes, in two distinct ways. First, Atlantic salt air accelerates the corrosion of metal exterior components and door gaskets – Halifax dishwashers on coastal-facing homes age faster externally than the same machines in inland Ontario cities. Second, hard well water in communities like Hammonds Plains, Fall River, and Sackville causes accelerated scale buildup on heating elements and spray arm nozzles, leading to earlier HE (heating) and OE/5C (drain) error codes as those components degrade. City water supplied by Halifax Water is relatively soft at 60 to 100 mg/L, so HRM homeowners on municipal supply see fewer scale-related faults than those on private wells. Running a monthly dishwasher cleaning cycle with a commercial cleaner like Affresh reduces scale accumulation regardless of water source.
