Dishwasher – Hotpoint BCI450 buzzing/humming

[sconners]

My dishwasher is 12 years old. When I start a clean cycle on my dishwasher it fills with water but when it’s supposed to start (spin the arms) nothing happens and it makes a buzzing noise.

After a couple of minutes (maybe a bit longer) it stops itself and gives an error (code) – illuminates 2 wash cycle lights (2&3 of 5 lights) – which I can’t seem to find anywhere on the internet.

I’ve had a quick look at the arms and they seem to be clear of any debris. Also, I don’t think that there’s any blockages because – as I’ve said above – the dishwasher fills with water and I can also here it drain and there’s no water when I open the door.

What [else] could be the problem? I read other articles with a similar issue and they mention that it could be the washer motor/pump. If it is the motor how can whether or not that’s the culprit?

Thanks and sorry for the long post.

Description does sound like a seized main motor, in theory it could be the capacitor but from experience the motor is the main culprit. At around £115 it would not be a viable repair on what is essentially an Indesit dishwasher.

I took the machine apart this morning (well, I took the bottom plate off) and your theory is right, the capacitor does in fact look like it has blown.

So, can I just replace the capacitor or do I need to replace the whole pump/motor?

Thanks

If you can find a capacitor of the correct value then it is well worthwhile giving it a try.
