Safety Boundary
Stop before live electrical work, pump removal, or leak repairs that require pulling a hardwired unit.
Start Here
- Cancel the cycle and listen for drain behavior.
- Check the filter, drain hose loop, and garbage disposal knockout if recently installed.
- Look for water in the base pan or under the unit.
- Record whether the code appears before fill, during wash, or at drain.
Decision Path
- Water left in tub: Start with filter, hose, air gap, and disposal connection before replacing a pump.
Next: Review drain and pump codes. - Leak or base-pan code: Dry visible water only if safe, then find whether the leak is door, hose, or overfill related.
Next: Use leak and float-switch code pages. - Poor wash or heat: Separate blocked spray arms, heater faults, and water-temperature issues.
Next: Compare heater and wash motor codes.
