Cold fill Beko heats on cold wash too!
I have a Beko 2313 CZ cold-fill standard washing machine. Recently it was stuck mid-cycle and water was VERY hot, even though it was on a 40C cottons programme, oh and the motor was not turning. Motor brushes found to be very worn and I replaced those. It then turned ok, rinsed etc, but still the water was very hot. Next, I checked the thermistor and compared the readings to a new one - same output, but fitted a new one anyway just to be sure; but the same result - the water was still becoming very hot. I then tried on 40C, 30C, and even COLD wash, but water still being heated by the element.
Does this sound like an expensive control board issue, or perhaps just the selector switch (see image)? If so, any way to test this selector switch? Or any other suggestions?

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Beko 2313 CZ heats water on all programmes including cold wash
- The problem
- A Beko 2313 CZ cold-fill washing machine overheated the wash water on a 40C cottons programme and also heated on 30C and cold wash settings. The machine had also stopped mid-cycle with the motor not turning, but after replacing very worn motor brushes the drum turned and rinsed normally while the overheating fault remained.
- Likely cause
- Most strongly supported diagnosis is a fault on the main PCB or a poor/broken connection in the temperature control circuit. A selector switch fault was queried by the owner but not confirmed.
- What fixed it
- No confirmed repair was documented. The accepted advice was that this type of fault is not easy to diagnose as a DIY job. Further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Motor brushes were found very worn and replaced
- Thermistor readings were compared with a new one and found the same
- A new thermistor was fitted but the fault remained
- Machine was tested on 40C, 30C and cold wash and still heated the water
- A short cycle was run with the selector switch disconnected and the water still became hot
- Parts or tools mentioned
- Motor brushes
- Thermistor
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

It could be an issue with the main PCB or even a poor or broken connection somewhere. This type of fault isn't easy for diy troubleshooting.

Ran a short cycle without this switch even connected. After 10 minutes the door felt warm, so I emptied the machine with the waste going into a bucket, and yep, the water was hot. As the switch circuit must default to cold for safety reasons (rather than the max 90C setting), I am thinking it's the more serious control board and/or mechanical control mechanism - both of which may prove uneconomical to start bothering with on a 14 y/o machine.
