Hi there. My duet shows a msg of .. f 01 I unpligged all the wiring from ccu and put it back, but didn't fix the problem. Do I really have to order a new ccu unit and will it fix the problem?

Answer Hello Sunny,
The F01 error code indiactes a Pump driver/Main Relay/EEPROM error. You will want to check for Loose power outlet, check to make sure unit is on a designated circuit. Make sure that the wire harness connections from the CCU are not broken or with wires detached. Make sure that all green wires are not broken or detached. Make sure that the 2 ground switches are pressed correctly by the toe and rear panels. Make sure all connectors are fully seated. Check for power going to the CCU by listening for a click in the CCU when unit plugged in. If problem persist and all checks ok then you will need to replace CCU.
