Random stops during washig cycle

Hi, I have a JLWM-1203 (over 10 years old) I replaced the heating element in it 6 years ago and motor carbon brushes 2 years ago.

The problem I'm having at the moment is that on any washing cycle the machine stops randomly.

The only way to get it going is to enable child lock, then when the machine stops, turn it off on the dial and turn it back on, this makes it continue with the cycle. It is John Lewis own one which I believe is a rebranded Zanussi

Been doing it for about 2 months, I checked the filters, there are no blockages.

The count-down timer also seems in accurate, usually gets to 1 minute left fairly quickly, then still goes on for over 30 minutes with 1 minute left on timer.

I suspected the controller, but in diagnostic mode (on 10th position of the dial) the code displayed is E-52, which would suggest a problem with the tacho coil on the motor.

From manual:

E52 No signal from the motor tachometric generator

Tacho coil on the motor is most probably faulty. This coil reads a magnet as the motor turns to detect the speed that the motor is spinning at and this in turn allows the electronic controller to set the motor to revolve at different speeds for the various program options.

Does this sound correct for the symptoms?

Thanks,

JLWM-1203 stopping mid-cycle with E52 fault

The problem
A John Lewis JLWM-1203 washing machine was stopping randomly on any wash cycle. The programme could be made to continue by switching the machine off at the dial and back on after enabling child lock. The timer was also reported to reach 1 minute remaining too early and then continue for over 30 minutes.
Likely cause
Diagnostic mode displayed E52, indicating no signal from the motor tachometric generator. The accepted reply said an intermittent tacho fault is more likely to be caused by a loose connection, as the tacho coil or magnet itself rarely fails intermittently. The inaccurate 1-minute display was also said to often be caused by an open circuit heater.
What fixed it
Check the motor tacho wiring and connections for looseness or poor connection. Also check the heater for an open circuit because that can cause the timer to stall at 1 minute. The exact repair was not confirmed in the discussion.
Checks to try
  • Filters checked and reported clear
  • Diagnostic mode fault code E52: no signal from the motor tachometric generator
  • Accepted advice to check for a loose connection related to the tacho circuit
  • Accepted advice to check for an open circuit heater

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

If it is then it’s likely to be a loose connection somewhere as it’s rare for a tacho coil (or magnet) issue to be intermittent. 1 minute left on display is often caused by an open circuit heater so check that too.
