Will the pump drain the water? The water level switch apparently thinks not.
To check the pressure switch at the CCU, perform the following steps:
1. Unplug washer or disconnect power.
2. Disconnect pressure switch connector
PRS2 (see page 4-5 in the manual below) from the CCU.
3. Set the ohmmeter to the R X 1 scale.
4. Touch the ohmmeter test leads to connector pins 1 and 2 on PRS2. The meter should indicate 0 Ω
What about error codes?Oasis Manual
