Re: Zanussi IZ161S Not Operating Correctly

Hi all again.
I want to upgrade this thread.

QER said they believed the board was good so I was reluctant to spend more money on a new board. Then I checked back on what TheSpinDoctor had told me previously, that if my Ohm readings were correct then the board must still be faulty.

So I eventually decided to buy a new Electronic Module.

On the last Saturday in June I picked up, and fitted the new Module to my daughters Zanussi washing machine, which I had ordered 8 days earlier from a local parts supplier. It cost £94, which was a lot, less than I had understood from some advertisements.

After I had configured it and started a wash programme, I anxiously watched to see if water was pumped over the inside of the door from the circulation pump.
It was a great relief to see it flowing and it went on to finish the wash.
It has been working perfectly for the last 2 months.

I am sorry to have been so long from my last reply on this thread but I had to stay in my son’s home to look after his youngest son during the school holidays, which started the next week. I am just home permanently yesterday.

I would like to thank TheSpinDocter very much for his invaluable diagnosis and help which he gave from the start of this thread without which I do not believe I could have fixed this machine, and also everyone else who contributed.

Thanks and Regards to all,
GRW1.

Re: zanussi zwf 12070

Hi,
When the fault has been repaired, is it not necessery to cancel the stored fault on the board before testing the machine.

I had one do the same 2 months back, entered the diagnostics,reset and away the machine went.

Hi A1TEC,
I know how to put the machine into diagnostic mode, but how do you reset the last fault.

Re: Zanussi IZ161S Not Operating Correctly

Thanks very much gandh1 for your helpful suggestions but EMW do not repair this particular Zanussi board.

It was my own PCB that was returned. After it did not work in the machine I did a diagnostic test and then checked the configuration.

I did not know how to do these tests until about a month ago. I have to thank these forums on UK Whitegoods for this extra knowledge.

All advice is very much appreciated.

Re: Zanussi IZ161S Not Operating Correctly

Hi Spin Doctor,

I have already fitted a new Circulating Pump as you had advised me earlier before I tried to get the Main PCB repaired.

I checked the new pump again by disconnecting J1 edge connector from the Main Board and connected my meter to terminals 1 and 10 on it, which is were the 2 wires from the circulating pump are connected to. The reading was 199 ohms.

I would very much appreciate any further help you may have.

Regards.

Re: Zanussi IZ161S Not Operating Correctly

Hi again,

Before sending the board away I checked the machine in diagnostic mode and error code E85 came up on the LCD when I got to the 9th LED.

I eventually sent the PCB to QER Ltd. to be repaired.

When it was returned I refitted it in the machine. When I started it up it operated just the same as I described in my first post.

I ran it in diagnostic mode again and still got error code E85. I blew down the circulating pump hose to check it was not blocked.

Could anything else cause this fault, other than the PCB, or is there anything else I should try.

Re: How do I code a non-configured PCB – Zanussi WJS1265W

Hi,
It looks like I may have to replace my daughters PCB Module for a Zanussi IZ161S, if I can’t get her original one repaired. All the new ones I have seen advertised are not configured.

Can you tell me if the configuration procedure above would be the same for her model Washing Machine, or if there is anything different in the procedure for her model?

Regards,
GRW1.

Re: Zanussi IZ161S Not Operating Correctly

Hi again,

As I could not get the part number for the Triac from my last post, my son fitted a 1Amp 600Volt one. He reckoned that should be ok as it was connected to a .20 Amp Circulating Pump.
I noticed a resistor on the back of the PCB directly behind the Triac which I did not think looked to good. There was no part number visible on it.

We went ahead and fitted the PCB but when we tried the machine it went the same as in my first post.

I was wondering if it was necessary to re-configure the PCB after fitting the new Triac.

Any further help would be much appreciated.

Re: Zanussi IZ161S Not Operating Correctly

Hi,

Could anyone with access to a GE PROCOND ELETTRONICA 356088503 PCB, or a Circuit Diagram for it, give me the part number for what I believe is a Surface Mount Triac in position TY8 on this board. The part number is not visible on the board I have.

Regards,
GRW1.

Re: Zanussi IZ161S Not Operating Correctly

Thanks again SpinDoctor. That’s good news about the wires on the circulation pump.

My son’s work is with electronics. He has looked at the PCB, a GE PROCOND ELETTRONICA 356088503, and noted that the “Triac”, TY8 is blown and that there is a considerable amount of soot on both sides of the board around the switcher, namely C1, C2, C5, C34, C37, T1, R1, R61, D4, D12 and IC5, that appears to centralise around R1 which is reading 4.8 ohms. He has asked if I could get a copy of the circuit diagram for the board or a part number for TY8 as the centre has been blown out of it and he can’t tell what it is. There are similar components on the board with markings Z9SY219 and Z9SY221 but he has had little success tracking down details of these components.

I would be obliged if someone could give me a part number for TY8 and, although I think it unlikely, information on where I could get a circuit diagram for the PCB. Finally, would anyone have any information regarding other known/stock faults on this board.

Regards,
GRW1

Re: Zanussi IZ161S Not Operating Correctly

I removed the back of the washing machine but there was too much in the way to see much of the pumps so I replaced it.

After another couple of tries through the bottom of the machine, I removed the drain and circulating hoses and was able to move the pump/drain assembly far enough to get an ohms reading across the two terminals. The reading was 29.5 ohms. I removed the 3 screws holding the circulating pump and took it out.

I eventually ordered a new pump DST1320156001, which is the newer model for this machine, and fitted it.

I think I put the 2 wires on the same terminals that I took them off but I’m not 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} certain. Does it matter which terminal each wire goes on too as it is an AC motor and booth wires look the same.

I assume the PCB, that controls the circulation pump, is the one the 2 wires from the pump goes to at the top back right side in a plastic case.

I numbered each terminal with a matching number on the plastic case with a permanent marker and asked my son to take out the PCB to see if he can fix it.

The PCB is a GE PROCOND ELETTRONICA 356088503

Is there likely to be more than a triac blown on the board.

Any more advice would be very much appreciated.

GRW1

Thanks again to TheSpinDoctor,

I will have another look at it this weekend when I visit my daughter.

Re: Zanussi IZ161S Not Operating Correctly

Hi,

On Sunday night I tried to take a resistance reading across the terminals of the recirculating pump, which I assume, is the pump at the right of the filter housing with a tube going up to the top of the drum over the door.

I laid the machine on its back and looked in through the hole in the middle of the thick plastic base using a mirror and a hand lamp. I thought I would be able to get at the pump by removing the lower front outer plastic panel. I took it off but there was no access that way as the metal case went down behind it.

I then removed the 2 hexagon head screws from the plastic base, which secured the filter/pump housing and manoeuvred it to the hole in the base but I could not see any bare terminals to take a reading from but there was 2 greenish insulated wires going into the pump housing. I had not disconnected any rubber hoses, as it is extremely awkward lying down to get at them.

It had got quite late so I had to reassemble everything and leave it to another day.

I was wondering if there was not an easier way into the machine to do this job but I couldn’t see any.

When I retested the machine there was no water circulating over the door.

Any further help would be very much appreciated.

Regards,
GRW1

Re: Zanussi IZ161S Not Operating Correctly

I would like to thank TheSpinDoctor for a very quick reply to my query about my daughter’s Zanussi washing machine.

I was not able to go to her house today, but I will be visiting her tomorrow and will bring a multimeter with me and check the resistance across the recirculating pump therminals.

I will let you know how I get on.

Thanks again TheSpinDoctor,
Regards,
GRW1
