What C5 describes
On a Kenmore 363 electronic-control dishwasher, C5 describes a drain that finished too quickly. According to the manual, that traces back to a tub that never filled all the way.
First, the easy items
The supply to the dishwasher should be opened all the way.
Inspect the overfill float switch. If it is lodged in the up position, the tub cannot fill as it should.
The inlet valve, step by step
Disconnect power and close the water supply.
Detach the fill line and examine the inlet water valve.
Inlet screen clogged? Replace the entire valve. Do not just clean the screen: leftover debris might hold the valve open and lead to flooding.
Any loose wiring connection at the valve gets tightened.
If the valve fails to open when it is activated, it needs replacing.
A C5 that outlasts these checks calls for a technician. In San Francisco and the Bay Area, (415) 825-6393 reaches us, and Kenmore dishwasher repair describes the work. Tell us the model number and whatever you tightened, cleaned or replaced.
Model compatibility: Kenmore reuses codes across series and model years, so C5 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
C5 reports a drain time that is too short because the dishwasher is underfilled.
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.
