⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: C1 Difficulty: Hard
Problem: Boiler temperature rising too fast.
How to Fix C1 Error (Step-by-Step)
- Turn off the dishwasher by pressing the power button, then disconnect it completely from the electrical supply by unplugging it or shutting off the circuit breaker.
- Open the dishwasher door and pull out the lower dish rack to get clear access to the bottom of the tub.
- Locate and remove the lower spray arm. Most models allow you to unscrew this by hand, turning it counter-clockwise.
- Inspect the heating element, which is the circular metal tube at the bottom of the dishwasher. Look for signs of heavy white or grey scale buildup on its surface.
- To clean the system, pour two cups of white vinegar into the bottom of the empty dishwasher tub. Do not attempt to scrub the element, as this can cause damage.
- Re-install the lower spray arm and the dish rack. Restore power to the dishwasher and run a full, empty wash cycle on the hottest setting to allow the vinegar to dissolve the mineral buildup.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
