The wash ends earlier than it should, and E:27 explains why: the spray diverter, or the small motor behind it, did not respond. Bosch lists a second cause for the same code, which is household voltage staying under 85 volts in the US. That starves the motor and gives the same result. A meter reading at the diverter separates the two cases.
1. Watch the kitchen lights when the dishwasher, the disposer or the microwave starts. 2. If they dim noticeably, write down which appliance does it. 3. Low voltage in the house is a wiring matter for an electrician. 4. If the lights stay steady, tell us, since that points toward the diverter.
Dimming lights, a humming fridge or other appliances struggling are clues. We can measure at the dishwasher during a cycle, and if it is low, we point you toward an electrician.
Yes, which is why the voltage check comes first. If the supply is good and the diverter still does not move, then the part itself has failed and needs replacing.
Not reliably. It tends to close the program early, so dishes come out partly cleaned. We would not keep rerunning it, because low voltage can strain motors.
A technician diagnoses it on site and gives you the price in writing before any work starts.
