Owners around San Francisco and the Bay Area can ask about DCS dishwasher drawer repair by phoning (415) 969-2271. Have U4, the code from the other drawer and your model number written down before you call.
Model compatibility: DCS reuses codes across series and model years, so U4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
