zanussi dw24 freeze

[bilbo99]

HI, our Zanussi DW24 dish washer wont run through a program, it keeps sticking, if you move the timer on it moves on a bit but then stops again.

I have cleaned out the filter and the little blue inserts under the screwed in cap.

I’ve been told it is stopping because of an anti flood device that is in a sealed unit that cant be got at?

You have only done half the job……… Have read of this:

Stay safe, power off if investigating.

Re: zanussi dw24 freeze

thanks for that, I had done that already with no joy.

Can I flush from the blue tubes through to the loop underneith? Incase there is a blockage in between?

The only thing I could see underneaith that I didn’t like the look of was part of a plastic bottle which appeared to be full of dark brown liquid.

Having read the other post it talks of this under the newer machine spec.

Is there a way of cleaning this?

The other thing I have seen is to use a wet vacume to suck out from the salt intake! Is this an option?

Re: zanussi dw24 freeze

Have you actually lifted out the tubes to flush them out? The horseshoe hose joins the two together underneath. Additionally, you should check the skinny pink and clear hoses which go to the inlet valve and the level switch. Neither should have water in. Can you hear a humming noise when the machine is meant to be filling? If you can, the valve is activated but may be being held closed by the anti-flood hose. The valve itself may have gone faulty with age – a sharp tap will sometimes revive it, although you should replace it at the earliest opportunity.

You didn’t say whether or not you got much goo out of the pipes. If there was very little, the valve is a more likely culprit.

The bottle full of dark brown fluid is the water softener unit and should not be disturbed under any circumstances.

Re: zanussi dw24 freeze

HI, thanmks for that. Yes I have taken out the tubes and flushed them.
The horseshoe had some gunk but they weren’t blocked.
The machine will fill but after a short while it freexes, you can manually turn on the timer but it again freezes after a while.

Which is the anti flood hose and how do I identify the valve?

Re: zanussi dw24 freeze

Inlet valve – where the water hose joins on. Anti-flood hose is an air hose connected to the valve, running back round to the sump area where the blue tubes sit. You are describing a classic “shut off” problem – machine fills once, then nothing.

Re: zanussi dw24 freeze

cant find the antiflood hose. Is it grey? If so it goes up the side of the machine from the inlet valve. If the inlet valve is directly where the feed hose connects.

The horse shoe is no v. clean and I can see through to where the blue tubes would be and there is no blockage.

Is ther a way of testing the valve before replacement?
Any idea of the cost of a new valve?

Re: zanussi dw24 freeze

right…. I have now cleaned out everything. There is nothing between the inside and the tubes underneith, they are gleeming!

The small pink tube is free from water and is the only tube I can find that runs from the inlet to the sump.

When we run the program, it will continue if we turn on the timer on but if left it freezes.

Re: zanussi dw24 freeze

Not much more I can tell you, Bilbo. Filling once and nothing generally means that the water level control switch has not shut off the water valve. It is operated by the short blue tube transfering air through the skinny clear tube, to the pressure switch. What will be happening is that the pneumatic shut-off on the valve is being operated by the long blue tube transferring air to the skinny pink tube and thence to the valve.

So – your problem lies with the short tube. The air hoses have been put back on the right way round? Does the level switch “click” when pressurised? It’s not full of water rather than air? The tube itself is not cracked or damaged?

Good luck,
Penguin45.

Re: zanussi dw24 freeze

The short tube you speak of, is that a clear small tube that comes out where the pink one comes out?

There is a thin round switch (I think) on the outer casing that the clear tube connects to. What role does this play?

The pink small tube sems to go around the sump and into the inlet vale.

Is the anti flood switch inside the inlet valve or are they the same thing?

There is no click at all.

Hi Bilbo
All the information and guidance needed has been given as far as possible.
If you are still in a dilemma then please feel free to use the engineer link below to find one in your area.

Re: zanussi dw24 freeze

HI, Thanks for that, but the reason I tried this site was because the engineer said it was a problem in the sealed part of the dish washer and to buy a new one!

I have replaced the inlet valve with no joy.

The anti flood is still kicking in. The small clear tube has water in it.

I tried allowing it to fill until it started to wash then turned off the supply manually to see if it just wasnt closing the inlet valve. But this still didn’t work.

I guess the engineer was right, although I can’t see what there is inside the sealed unit!!

Re: zanussi dw24 freeze

The small clear tube should not have water in it. There is an air leak, somewhere.

Beyond that, I’m out of things to tell you.
