First things first 🙂
Remove the spray arms and thoughly clean the spray jets.
It may not be heating and/or recirculating due to low water level or heater may well have failed.
If heater ok, worth checking the usual solder problem on relay pin on module 😉
Worth checking the ribbed clear hose behind the lower panel below door. This can be removed and cleaned as it only o rings in either end.
The water matrix and the metering unit (both lhs behind side panel; get crudded for the sake of not giving the plates a quick swill under tap before loading.
The sensors are inaccesible tbh. Running hot cycles eventually may clear any crud.
Not draining in between could be down to not reaching temp or a tired drain pump. Check above first then move to drain thought.
Power off if you are to attempt any of this :plug:

I’ve checked and cleaned the arms and top jet (this one was quite clogged)

Heating seems fine and water level is well above the filter.

The machine will fully drain in about 30 seconds so I guess the pump and ways are OK.

I’ll take a look at the other items whan I have time. Thanks

blombergs do not attempt ANY spin if the load is found to be unbalanced during the distribution process, and thats why it stopped with the pump running after trying to distribute the load, answered ur own question!

penguin was spot on with his diagnosis, what you did did not cure the problem cos there wasnt one, although its a bonus having the thing cleaned out, and no, they dont have a memory

… except that it did not even run the distribute and therefore could not have detected an out of balance condition. It didn’t stop; it never started.

A load which will not even out can cause the motor to accelerate and decelerate excessively. The computer side of things can decide that this is excessive and will not spin the load.

Penguin45.

Thanks for the reply.

I’ve now read up a bit on how the out of balance works on these machines. As I understand it it does a low speed ‘test’ spin to determine the out of balance from the motor tacho. Short term variations in the speed with a repetition at the drum rotation rate show an unbalance. The amplitude of these speed variations gives the amount of unbalance.

In my case the machine would not even attempt this ‘test’ spin. It would perform the initial attempt to balance the load but then stop with the pump running; as though it had detected an imbalance. It did this many times when I tried it last week.

I think it has something to do this the level sensor. This was clearly blocked when I cleaned it. I just wonder if the computer stores the fault if it happens often enough then requires a few runs to clear it (a little like OBD in vehicles)

Re: Blomberg 1501 No Spin – Not the normal problems

Well, I checked the two diodes on the control PCB – OK.
Removed the pressure switch and checked continutity – OK on all four settings.

(The four are 1-Low ; 2-Medium; 3-High; 4-Overfill)

The machine uses:-
A N/O contact on the medium setting for the heater.
N/C contacts for the sensing the other four condtions.

Anyway, put it all back and … it span first time.

Running a full cycle (empty) at 90deg.

But I really don’t know why it’s working now.
