Zanussi ZWF1437 Error E30

Recommended Posts

Have had the above machine for many years, new drum bearings and motor brushes done a few years ago.
Never had any issues with the machine, just done the above as a matter of routine due to age.

Recently, if starting a 2nd wash straight after the first finishes the machine appears to start correctly,
Wash light on, Drain pump runs but instead of the drain pump stopping and the machine filling with water
the wash light goes off and the Drain light comes on, extended drain cycle performed and machine stops. E30 displays.

Leaving the machine for a while it starts and works ok, sometimes it will do a 2nd wash without failing.

I suspected the pressure switch but replacing it did not fix the issue.
I have checked the pressure pipes and removed the pressure chamber, all clean.
The drain pump does empty any water in the machine.

The user manual does not list any E3x errors, just the following
- E10 : problem with the water supply
- E20 : problem with water draining
- E40 : door open

This machines owes me nothing but its part of the family :D That said I don't want to start throwing money at it now.
Have been looking for a replacement but put off by long cycle times and/or inability to do a quick wash with
a fast spin! 

Seem various posts on other forums and even found the exact same issue but no resolution.

Any thoughts before I have to put it into retirement greatly appreciated.

Hello. No my Zanussi error codes don't list E30 either. Your description of the fault got me thinking of blockage in the pressure chamber but if it isn't that, it's hard to think of anything that would only happen after a successful wash cycle other than something overheating in the pcb but that's a long shot. If you leave it a few hours after a wash cycle has finished, does everything work ok then?

Hi Andy, thanks for the reply.
It did the usual this morning, worked once then failed, I was ready to order a new machine but thought to give it a last chance.
On checking the brushes I noticed 2 things, firstly the connector to one of them was a bit loose and secondly that the motor made an unusual noise when it turned in one direction.
Removing the brushes, one of them had split, seems that the brush is made of 2 pieces of carbon stuck together.
Fitted new brushes and crimped the connector a bit.

Went through all the connectors, re-seated and checked for any trapped wires etc. Everything else looked good.

Just started second load ok.

Odd that this code is not mentioned anywhere so I was just going by symptoms.
Fingers crossed it was the brush.

Thanks for the update. Hopefully that’s it. I was going to mention a poor connection somewhere but it made nonsense that a poor connection would always hang on until one wash before causing trouble.
