hotpoint WMA 37 fault lights??

[chris25]

Hi

please can anybody offer advice as to why my hotpoint WMA 37 stops mid cycle. The Wash, Rinse and spin and final spin are all lit but not flashing. The machine did not reach the spin but has drained the drum before it stopped.

Hotpoint Error Codes courtesy of Rocks1

f01 light 4, motor triac
f02 light 3 motor, jammed/ tacho
f03 lights 3&4 Ntc fault
f04 light 2. pressure sw stuck on empty
f05 lights 2&4, pressure sw stuck on full
f06 lights 2&3, N/A?
f07 lights 2&3&4 heater relay
f08 light 1. heater relay
f09 lights 1&4 eprom/setup error
f10 lights 1&3, pressure switch not sensing
f11 lights 1&3&4, pump/draining error
f12 lights 1&2, communication error
f13 lights 1&2&4, dryer ntc/ fan motor
f14 lights 1&2&3, dryer heater
f15 lights 1&2&3&4, dryer heater relay
f16 N/A
f17 light 4, door lock
f18 light 3 comms error (3 phase motor) power board

So in this instance with the second light flashing the error code would be f04 light 2. pressure sw stuck on empty

Hotpoint WMA 30/40/50 LAST ERROR DETECTED codes

Ensure that the main selector switch is in the Off or O position.

Press and hold the Super Rinse and Rinse Hold buttons whilst selecting H on the selector knob, and continue to hold for five seconds.

The 'Super Rinse', 'Rinse Hold' and 'Wash' LED's will now be flashing.

Press the Start/Cancel button for two seconds.

The 'Rinse Hold' LED will be lit and the 'Super Rinse' LED will be flashing.
The 'Final Spin' LED could be on or off at this stage.

Press the Rinse Hold button briefly.

The 'Rinse Hold' LED will be flashing & the 'Super Rinse' LED will be on steady to indicate the last error routine has been initiated.

Rotate the main programme selector knob slowly anti-clockwise to programme A

Slowly rotate the selector switch clockwise through four positions A to D inclusive, pausing briefly at each programme position. Starting with A make a note of the 'Final Spin' LED status. it will be on or off.

When the selector knob reaches D you will have a series of Ons and Offs . This 4 bit binary code should be recorded and checked against the error codes in the following table.

..............................................................A...........B.............C...........D

No spin due to O.O.B............................on.........off...........off.........off

Start butt pressed with door open.......off..........on............off........off
or O/C interlock.

Failure to fill in allotted time.................on..........on..........off..........off

Failure to pump out in time allowed......off.........off.........on..........off

No feedback from thermistor when......off.........on..........on.........off
heating.

Tacho error...........................................on........on..........on...........off

No feedback from tacho.......................off..........off.........off..........on
Motor O/C

Motor triac short circuit.........................on..........off..........off..........on

That was a bit of a pain to get lined up but I hope someone may find it useful.

Thanks Very much for your replies

i have carried out the procedure and i have the binary code of 1001 however you have 2 errors for this code.

Can you explain the two errors "no spin due to O.O.B "

and "Motor Triac short circuit"

 

[chris25]

Crying or Very sad

ok what was in the mc before the prob was it 1 item or full load .1 item dont spin on this mc .does the mc spin empty put on a rinse prog when its stopped filling put onto spin and see what happens.

 

[rocks1]

looks like motor brushes fault , check the brushes on the motor.

 

[chris25]

the machine had a 3/4 to full load in nothing heavy. The machine ran for about 30 minutes on wash and then it drained the water as i heard the pump run. It then stopped with the 3 lights on. I then turned the dial to Off and started the rinse and spin program. The machine ran the rinse and spin program. However when i read your post i turned the dial to Off and tried you r procedure. I am not sure if i caused the triac fault by powering down the machine.

 

[chris25]

i have put the machine back on wash and i am waiting to repeat binary code procedure !!!

 

[rocks1]

see u within the hr

 

[chris25]

Now it's an intermittent fault the machine has just ran through a cycle completely, the only difference than before was that i have set it to time saver mode??javascript:emoticon('')
