Dishwasher leak service in San Francisco
Water under a dishwasher is a reason to call: our San Francisco team at (415) 449-0036 works across the Bay Area, and Electrolux dishwasher repair explains the work. Have the code, the model number and the time you switched power off ready.
Model compatibility: Electrolux reuses codes across series and model years, so Er01, Er 01 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Er01 means the leak detector has detected water under the tub of an older EIDW6105 or EIDW6305 built-in dishwasher.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
