    Bit of a long story here, the customer reported that the machine isn’t drying. It washes fine but not drying at all.

    Checked the stats, all checked out
    Checked the wiring connections for the dryer components such as fan, thermostat, heater and all seems to checked out from the plug at the module to the dryer.

    Has it been known for the module to fail especially with heater relays on the board?

    Thankyou, got the info and the machine came up with E73 which suggests washing machine thermostat. I was given this code by “google” 1328302003. Trying to pinpoint where is this is located? Seems odd that the dryer not responding and the info implies it’s the washing machine heating, maybe both are interconnected?

    Looking in the all the service manuals that I have lists E73 as “Fault in NTC sensor on drying duct (voltage out of range, short-circuit or open circuit)”

    I agree with Dave on this one – remove the tape from the wires to the NTC on the dryer duct and you will probably find the fault.

    Thanks Dave and Jem,
    found the fault lies within the wires to the NTC hidden behind the tape. It was on the bend where it flexes in the void between the dryer duct and the top carcass, it made a clean break on both wires. Repaired the connection by rejoining and strengthening the bend by stiffening up.
