How to Fix Bosch Dishwasher Error E27
Error Code: E27 Difficulty: Easy

Problem: Low voltage in the power supply.

How to Fix E27 Error (Step-by-Step)
1. Locate your home’s main electrical panel and check if the circuit breaker dedicated to the dishwasher has tripped. If it is in the middle or off position, flip it fully off and then back on to reset it.
2. Ensure the dishwasher’s power cord is pushed all the way into the wall outlet. Sometimes vibrations can cause it to become loose.
3. Examine the entire length of the power cord for any visible signs of damage, such as cuts, burns, or frayed wires. A damaged cord can cause voltage issues.
4. To verify the outlet is working correctly, unplug the dishwasher and plug in a small, known-working appliance like a lamp or a phone charger.
5. Dishwashers should be on a dedicated circuit. Remove any extension cords or power strips and plug the appliance directly into the wall outlet.
6. If these steps do not resolve the issue, the problem may be with your home’s wiring, which requires a professional electrician to diagnose and repair.
7. Turn the appliance off, wait about 2 minutes, then turn it back on.
