How to Fix F27 Error (Step-by-Step)

Ensure the washer is unplugged from the wall outlet and confirm the error stays cleared during a full test cycle.

Gently disconnect the wire connector and the hose from the old pressure sensor.
Remove the old sensor from its mounting bracket and confirm the error stays cleared during a full test cycle.
Install the new pressure sensor onto the mounting bracket and confirm the error stays cleared during a full test cycle.
Reattach the hose and the wire connector, then reassemble the washer.
Turn the appliance off, wait about 2 minutes, then turn it back on.
