Zanussi Z9282T only partially draining

[garfy_99]

Hi,

My Zanussi Z9282T has just developed a draining problem. It seems to complete all the cycles properly (including spin cycle), but the clothes come out very wet. Closer inspection shows that the water has not fully drained.

I’ve checked the pump – it is spinnng and the blades do not look damaged. Water is pumped out into the drain lwith a good amount of power.

I’ve checked all the tubes going into and out of the pump. I did actually find 3 coins in the drum water outlet, but removing these doesn’t seem to have solved the problem.

Any ideas?

Thanks

Simon

That’s an oldie……. 5p in the outlet tube of the pump was always a good one – it can act as a flap valve. The rubber outlet hose (if still fitted) was prone to nipping, crushing and internal collapse. The pump may be overheating and cutting out after a short while – don’t forget that the water is extracted in two stages; the free water, then what is held in the laundry.

If it has the original “Washcraft” range air chamber (grey plastic moulding screwed to the drum) it may well be blocked. It may however either have the newer (or as a modification) “tube” type air chamber (both types connect to the sump hose), which ever it has if the machine drains but no spin I suggest a blocked air chamber. The early grey moulded type aren’t available to the best of my memory as they came at the end as a mod kit including the “tube” type air chamber.

Forgot one – droopy sump hose can airlock the pump. Haven’t had to do one in years. Part number was 50097100-00/7 – I think one of the wholesalers still does it under 37-ZN-14.

Email to spares@ukwhitegoods.co.uk should you wish to order.

Well thanks for advice – all tubing seems to be fine. I think the air chamber may be blocked (it’s the original grey plastic box) – problem is I don’t know how it’s supposed to behave. If you blow hard in one end, a little bit of air comes out the other end, but then stops. If I put water in one end, it slowly trickles out the other. Is this what it’s supposed to do? Is there a good way to clean it out?

Thanks again

sounds like its blocked not easy to clear, may need a new one.

To clear.

1 take the thing off with pipe to p/switch attached. Do not do this with machine leaning back as water will enter the motor & write it off.

2 Pop a couple of 10mm sized nuts into the housing and with a soapy solution give it a shakety-shake. Use a powder, not washing up liquid.

3 As per Haynes manuals, reassemble in reverse order.

4 If not the cause of the problem, take a look at where the waste hose goes, and if connected to a sink trap with a branch off, give the nozzle a clear. Assume the filter in the front is clean.

Re: Zanussi Z9282T only partially draining

Thank for all the advice – but oh no – WHAT HAVE I DONE!

I cleaned out the air chamber – as per Alex’s suggestion and that seemed to go well. I put it all back together again – and now it’s refusing to fill with water.

In fact when you turn it on, it does nothing – it’s at this point it would normally fill with water. I’ve checked that there is power coming into the machine, and I’ve checked there is no power sent to the water valves – so they can’t be faulty. The pressure sensor also seems to work (it clicks when you blow into it).

The only area I’ve worked on is the hoses, tubes, air chamber and filter, so what could I have done? I’ve not touched anything else!

Thanks

First thing to check, when you pull out the knob, does the green indicator light come on?

Next, try and see if you can open the door, if so the lock didn’t engage.

If both the above is o.k. does it do anything? for example attempt to pump when set to the drain cycle?

Re: Zanussi Z9282T only partially draining

Yes – the green light is on.
Yes – the door lock is engaged.
I haven’t seen it attempt to pump, however if I move it to the spin cycle it starts spinning (even though there is no water on the machine).

If I put it at the beginning of a wash cycle, and activate the pressure switch by blowing into the tube (presumably fooling it into thinking there is water in the drum), then the timer jumps into life and starts ticking, and the drum starts turning.

Re: Zanussi Z9282T only partially draining

On the earlier ones the neutral for the water valves was fed through the pump winding. Don’t ask why?

Does the pump show any sign of leaking? If so it is on it’s way out, and the chances are when it gets hot the overload in the cut out in the winding opens and hey presto, no fill next time. Will also explain why the drainage was poor as the pump would be cutting in & out.

Pumps are still available.
