Broadly agreeing with the above in this case, something else is probably failed short-circuit causing excess current through these components.
Changing components such as power transistors can be OK though as they fail relatively frequently.
Interesting. I just read kwatt’s post,
You can solve the problems through the use of technology, like turbidity sensors but they aren’t the most reliable of things and push the price up
The Bosch I referred to earlier is a hydrosensor model so perhaps that’s why it seems to cope with basically whatever detergent I do (or don’t) put in it. But only ever noticed exess foaming when it was washing bamboo nappies.
Just goes to show there is a lot more to these computer controlled washing machines than it first seems.
Quickwash – thanks for the pointer on the cleaner, I’ll give that a go.
Cheers
Just for interest on some of the points in this thread, on my washer (Bosch) the pre-wash is cold and the hot-fill is used for 40*C+ washes (topped up with cold after a little bit). As a household with young children, I find pre-wash very useful indeed!
Anyway that too washes well with much less detergent than specified BUT after 10 years there is quite a build-up of hard white scale/scum which perhaps is due to insufficient water softening? The build up is sufficient to prevent the coin catcher being removed sometimes and the bottom hose is quite ‘crunchy’ feeling when squeezed (after which a load of hard blobs get washed through).
Is there any movement in the inner drum up-and-down relative to the outer drum – i.e. if you push up on the front of the inner drum (where you put the clothes) can you feel play in it?
Be *very* carefully with the tester – it can and will present 500V (or more) between the wires which very obviously is extremely dangerous. Keep in mind that the entire machine is made of metal – you really don’t want to be touching it!
It will also destroy any connected electronic circuit boards which potentially could include parts of the motor (only the windings should be tested).
And of course, unplug the machine before you start.
Strikes me the OP should really be persuing the retailer that supplied it for this, it doesn’t seem to me reasonable given the price of it… Sale of Goods Act and all that.
Yes not doubting that… just interested in what it was 🙂
Running well thus far – back to like when it was new, about 68dB(A) spinning at 1600rpm full load measured from 1m in front of it.
Interesting. Turns out there are special greases for this application like “Amblygon TA30/1”. As said above the grease needs to work at 90*C+ and be resistant to water and steam and also alkaline. I’ve gone with the small pot from our hosts… no detail on what it actally is was included unfortunately.
Right, bearing change take two… firstly cleaned up the shaft a bit more:
Then wiped over with grease for protection:
And grease in the rubber seal ready for fitment:
The squeak has now gone and the drum rotates noticably more easily now 🙂
Cheers!
Thanks, we do run service washes but obviously not often enough.
I just noticed our hosts have a grease that looks to be specific for the job….
Cheers!
