So to start, let's go over the error and what it means as well as what can cause it.
PRESSURE SWTICH ERRORThe wash level and level heater safety are switched on at the same time F23Possible Causes/Procedure1. Unplug washer or disconnect power.2. Check wire harness connections to pressure switch and Central Control Unit (CCU).3. Check connections of the CCU board within the housing.4. Check the pressure switch for worn or failed conditions .
To access the pressure switch and the CCU, you'd have to pull the washer out and if you have a dryer stacked on top, you need to remove the dryer because the top panel of the washer needs to be removed. Unplug the washer, remove the screws coming in from the back of the top panel, and the top panel will pull straight back, up, and off. Now you can look for the pressure switch in the back right corner which will have a small rubber hose and several wires going to it. Disconnect the hose and blow through the hose to make sure it's clear to the bottom of the tub. If that all checks good and the wires between the CCU and the pressure switch are secure, then replace the pressure switch.
