What does the error code on my dishwasher mean?
Most common cause on a dishwasher in the GTA: drain fault — clogged filter/pump/hose (Bosch E24/E22, LG OE, Samsung 5C/5E, Whirlpool 8-flash). A typical repair runs $180–$510 all-in, including the $149.95 diagnostic, credited 100% toward your repair. Most codes are non-emergencies; a leak code (Bosch E15) is more urgent because it means water reached the base. Book at convenience

Error code flashing$180–$510
Error code flashing: A code shows on the display (or a status light blinks a set number of times) and the cycle stops or won't start.
Also described as: flashing lights, error on display, blinking clean light, fault code, E15, E24, OE, 4C
Likely causes
- Drain fault — clogged filter/pump/hose (Bosch E24/E22, LG OE, Samsung 5C/5E, Whirlpool 8-flash) (Most common)
- Water-supply/fill fault — closed valve, scaled inlet valve, float stuck (Samsung 4C/4E, LG IE, Bosch E3) (Common)
- Leak detected at the base pan — Bosch E15 / AquaStop tripped (often a reset + dry, not a part) (Common)
- Heating, stuck-key, or control-board fault (Whirlpool F2E1 stuck UI key, various heater/thermistor codes) (Occasional)
How we diagnose it — in order
- Read the exact code first: on display models note the alphanumeric code; on light-only models count the blink pattern (flashes between pauses) and match it to that brand/model's fault chart. The code tells you which system to check (fill, drain, heat, or control) so you aren't guessing.
- Clear transient faults with a hard reset: kill power at the breaker for 5 minutes, restore, and run a short cycle. If the code does not return, it was a one-time glitch (power blip, stuck cycle); if it comes back, the underlying fault is real and you proceed.
- If the code points to a fill/no-water fault, confirm the supply: verify the under-sink saddle/shutoff valve is fully open, check the inlet hose for kinks, and pull and clean the fine mesh screen at the inlet-valve inlet, where GTA hard-water scale commonly clogs it. Re-test before condemning the valve.
- If the code points to a drain/standing-water fault (the most common mechanical cause), pull the sump filter, remove the drain-pump cover, and inspect the impeller with a flashlight for glass, bones, or labels; clear it with needle-nose pliers. Then check the drain hose and that any new disposer knockout plug was removed.
- If the code points to a heat/thermal fault, test the thermistor and heater circuit (technician only): check the thermistor's resistance against spec, inspect its wiring/connectors, and confirm the heater is getting and reading voltage so you know whether the sensor or the heating element is at fault.
- Only after fill, drain, and heat circuits test good, condemn the control board: with the matching system checking out and the same code persisting after reset, the main control has an internal fault and the board (and on some brands the ribbon/cable to the touch panel) is the definitive replacement.
✔ Safe to check yourself
- Note the exact code (or count the blinks) and look it up for your brand — it points straight at the subsystem.
- Try a hard reset: power off at the breaker for 5 minutes, then restore — clears transient faults.
- For a drain code, clean the filter and clear standing water first; for a fill code, check the supply valve and float.
- For Bosch E15: this is the base-pan leak float — power off, slide the unit out, dry the base tray fully, then restore power. If E15 clears and stays clear, it was a one-time tilt/condensation/over-suds event, not a failed part.
✖ Leave to a technician
- Don't keep clearing a leak code (E15) and re-running — if it returns there is a real leak to trace, and running risks the control board.
- Heater, pump, control-board, and sensor diagnosis needs a meter and tear-down — technician job.

Brand-specific patterns we see
- Miele: Miele dishwashers are the category's endurance machines (factory-tested to a 20-year design life, the original 3D cutlery tray) with a disciplined fault language: F11 (drain path/filter), F12/F13 (water inlet blocked), F14 (pressure/level switch governing water level for heating), F24 (heater-relay), F70 (waterproof-system float found water in the base), F78 (circulation pump), and on G7000 F600/F601 (AutoDos: F600 = dispensing outlet fault, F601 = PowerDisk-holder seating). Parts run factory-leaning — orderable but not GTA-shelf-stocked like Bosch/GE — so the role is honest triage between same-visit filter/debris/maintenance fixes and sealed-module swaps ordered against the serial.

Repair or replace your dishwasher?
A simple rule of thumb: if the repair costs more than half the price of a comparable new unit and the appliance is near the end of its life, replacement may make more sense.
A dishwasher typically lasts – and costs $600–$1,200 to replace — so most faults under about $450 are worth fixing. We'll always tell you honestly when a repair isn't worth your money.
Keep your dishwasher running
Simple habits that prevent the most common the GTA repairs.
- Clean the bottom filter monthly — twist it out and rinse under warm water; a clogged filter is the #1 cause of poor cleaning and drain faults.
- Pull the spray arms a few times a year and clear the jet holes with a toothpick so water reaches every dish.
- Keep the rinse-aid reservoir topped up — it's what sheets water off so dishes actually dry (essential on modern condensation-dry models).
- Run a dishwasher cleaner (or a cup of white vinegar on a hot cycle) monthly to clear grease and hard-water scale — Toronto/GTA water is moderately hard.
- Use only dishwasher detergent — never dish soap or hand soap, which foams over and leaks past the door seals.
- Wipe the door gasket clean and check it for tears; replace it as soon as it hardens or leaks.
- Scrape plates instead of pre-rinsing them spotless — modern detergents need some food soil to work against, and heavy debris clogs the filter.
- Run the kitchen hot tap before starting a cycle so the dishwasher fills with already-hot water for better cleaning and drying.
