We replaced the circ motor and inline heater on this machine after one of the hoses split and soaked both parts. Since fitting these parts we are getting an F6 error code after about 4 minutes on any cycle. Whirlpool error dept ( ❓ ) say this is suggesting no water supply but the tap is on and the machine fills to level with no problem. The turbidity sensor in the sump looks a bit blackened (inside the glass capsule) but other than this everything seems OK. I’ve checked all connections on the module etc to no avail. Any suggestions please?
The other thing to check / do is pull off the flowmeter plug at the flowmeter and plug it back on again. Dodgy connection brings up F6.
Most likely, as Dave said, the pressure switch is the cause.
