Dear All,
New to the forum.Our AWOD6727 (859296915003) [ser no 410911016483] recently reported ‘CLEAN PUMP’. It had stopped mid cycle.
I drained it, cleaned the Plaset magnetic pump (usual obstructions – a small coin, a clip, a button etc), checked the drain outlet was clear and pipe not kinked, and restarted it on rinse and spin. It repeated CLEAN PUMP at drain time.
I replaced the pump with an identical Plaset, and tested it with drain and spin. Once again it it stopped when it should drain and reported CLEAN PUMP…
Any ideas guys?
Cheers and thanks in advance

machine will report clean pump if it thinks it still has water in it
inside machine you will find thin tub going to a switch at the top of the machine but it has a chamber at the bottom that traps air. if this chamber is clogged it will assume it is still full
beware dont blow into the top switch. some of the later switches are damaged by this and i cant be sure which type of switch it is in this model

Hi Dave,
Many thanks. I will have a look at this switch and tubing and report back here.
Cheers

Hi Dave and All,
I checked that the pressure switch (black) tube is clear, and that the air chamber, located at the back right, is also clear.
Also check the drain hose for blockages.
I checked the new pump. It has a resistance of 193 ohms and it runs outside the machine when 240 volts is applied.
So I tested it again after checking hose and top black tube and air chamber on outlet. I ran rinse and spin.
It STILL stops when the pump is supposed to activate, and says CLEAN PUMP.
Do you think the pressure switch has failed?
What else could I try??
Thanks in advance

Dear All,
just to conclude this one, I tested pressure switch, which seems to be working fine. Checked all connections including earths. Problem persists, so I think it is the control board that is damaged. This makes the machine beyond economic repair. Used control board/front panels are available for about £30. I can see no point in that as they are untestable by me. A new one comes in at about £150, which seems to me like a deliberate way of making the machine economically unrepairable.Thanks so much for help received here. Hope this thread is useful to others.
The machine was heavily used domestically, and ran for about 5 years.
I recently replaced the door seal (inexpensive but very fiddly), but otherwise it had no other problems until now.
Some reviewers reported early bearing failure on this model, but we saw no signs of that.Re: Puzzling Problem with AWOD 6727 Pump…any ideas?
Hi Martin,
What would be the easiest way to test that? Presumably it’s on the same circuit as the pump?
best

Easiest way to test the heater is with a multimeter on the M’Ohms scale. Anything below 3M’Ohms to earth i’d imagine would cause problems.
Its possible that the triac on p.c.b supplying the pump has failed/burn’t out because the pump was running excessively because of coins etc stuck in it.
As with all Electrical products, power off when doing any tests.
