Error Code: E29 Difficulty: Hard
Problem: Low mains voltage; the dishwasher is receiving insufficient voltage to operate.
How to Fix E29 Error (Step-by-Step)
- For your safety, first unplug the dishwasher from the wall outlet or turn off the corresponding circuit breaker in your home’s electrical panel.
- Go to your home’s circuit breaker panel and locate the breaker that supplies power to your dishwasher.
- If the breaker is in the middle or ‘OFF’ position, it has tripped. To reset it, push it firmly to the ‘OFF’ position, and then back to the ‘ON’ position.
- Test the power outlet itself. Plug a small, working appliance like a lamp or a phone charger into the same outlet to see if it receives power.
- If the other appliance does not work in that outlet, the problem is with your home’s electrical supply, not the dishwasher.
- Do not attempt to repair home wiring yourself. This error indicates a problem with the voltage your home is supplying to the appliance.
- You must contact a licensed electrician to test the voltage at the outlet and diagnose the electrical issue within your home’s wiring.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
