Flashing light on JLWM1407

[theelmani]

Hoping you can help. The start button on my JLWM1407 flashes green but won’t actually start when I press it. I though the problem was with the door as the plastic was broken, I replaced it but still no joy. Any thoughts? Thanks

Re: Flashing light on JLWM1407

if you look at the button when it flashes is there a pattern

ie 4 flashes then a break then 4 flashes etc

Thanks for your response Dave. No, it just keeps flashing on/off consistently. Adam

Child lock is not on. I’m assuming the PNC number is the Prod No? it’s 914522515 00
Thanks

Re: Flashing light on JLWM1407

right try this
1. Switch off the appliance.

2. Press and hold down the START/PAUSE button and the nearest OPTION button simultaneously

3. Holding down both buttons, switch the appliance on by turning the programme selector one position clockwise.

4. Continue to hold down the buttons until the LEDs begin to flash (at least 2 seconds).
In the first position, the cycle tests the operation of the buttons and the relative LEDs.
If the selector is turned clockwise, the cycle performs the diagnostics for the various components and reads the alarm codes.

after you in this mode in position 1. turn the knob clockwise to position 10. this will give the last error code. All other switch positions test various components

position 2 door interlock and wash solenoid
position 3 interlock and pre wash solenoid
and so on

try position 2 at least we know door lock ok if it works

Thanks – on position 2 the led turns red and I get error code E51?

Re: Flashing light on JLWM1407

E51 is motor traic short circuit
yes it could be this would need a new one soldering into the board or a new board but poss faults to get same result are

earth fault on motor. can be damp (had condensation on one once causing this). Also check carbon brushes. as they wear they give off carbon dust which is conductive so take each one off and clean them
