Indesit Iwdd7143 Washing Machine Not Draining Water, Pump Failure
I have an Indesit IWDD7143 washing machine and dryer combo. It had initially fail to drain water out and water was leaking from the ceased drain pump onto the the floor. I then opened the pump and cleaned it out, I found a hairpin, and also found some coins in the drain sump. I did not buy this washing machine from new so could have been from previous user.
I replaced the drain pump for a new one of the same type, however it still does not drain. Everytime the machine comes to the cycle it needs to drain it would stop. Even if filled with water and I want it to drain using the drain mode, after 2 mins of nothing happening it may put the F11 error on. I checked the voltage to the pump and it is getting 152volts AC, I do not know if this is enough, I guess it needs the full 230v AC to spin the pump.
I even opened the PCB module after and found a burnt out varistor TVR07471. I tried to find it online and no where in the UK seems top have them; nearest value I got was Varistor 180 pF 25 A 775 V from RS Online. I fitted this to the circuit board, but still no cigar.
My last option I guess is to pay £94 for a new PCB module. Does anyone else know any different what would cause the pump not to run.
My PCB code is 215011572.01 S/N 1318404682 SW 16.00.19
Solution Summary
AI-generated from this discussion
This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Indesit IWDD7143 would not drain and showed F11 despite a new pump
- The problem
- Indesit IWDD7143 washer-dryer stopped at drain stages and would not pump out water. The original drain pump had seized and leaked; debris including a hairpin and coins was found and removed. A replacement pump was fitted but the machine still failed to drain and later displayed F11.
- Likely cause
- Most strongly supported cause is a poor connection or wiring fault in the drain pump circuit, particularly at the PCB-to-pump connector pins. The repaired control module may also have had damaged components, but the final successful result followed attention to the wiring connectors rather than further board replacement.
- What fixed it
- The original PCB was sent away for repair after an unsuitable replacement board produced F09 because it was not programmed. After the repaired original board was refitted, the machine still showed F11 until the connector linking the module to the drain pump was removed, the pins tightened at both ends, and the plug refitted firmly. The machine then drained correctly.
- Checks to try
- Pump opened and cleaned; hairpin found
- Coins found in the drain sump
- Drain pump replaced with a new one of the same type
- Voltage to pump checked and reported as 152V AC
- PCB inspected and found with burnt varistor TVR07471
- Replacement PCB fitted and produced F09
- Original PCB professionally repaired with a varistor and four other components replaced
- Drain pump wiring connector at the module checked and pins tightened at both ends
- Parts or tools mentioned
- Drain pump
- PCB module 215011572.01
- Varistor TVR07471
- Replacement PCB 21501022702
- Original PCB repair service
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

They don't sell spares for pcb boards, or at least the manufacturers don't sell them - only complete boards. If the pump didn't have a neutral return it wouldn't run.

After the problems with my old PCB module, I had bought a new board of Amazon, plugged it in and it gave a F09 fault. Called the company up and they said no it is not programmed, was very upset especially as it was listed for the IWDD7143UK.
I have almost given up with this as it seems no one may repair the old board.
Strange is the new board is made by Delta Electronics, INC
Code:21501022702
S/N:1404304387
FW1:16.00.13
Long bar code:131215010227021404304387
The old one is made by COMPUTIME
Code:215011572.01
SW:16.00.19
S/N:1318404682
Long bar code:091215011572011318404682
Any advice anyone?
F09 on Indesit washing machines is usually "EEPROM error" which is the software chip. New ones often need setting up and programming as they are often the same boards for different models with different features and wash cycles. They shouldn't really be selling boards to the public if they need configuring without at least mentioning it. I wonder if it's possible to put in the old chip from your old board?
Other than that try researching Indesit eeprom. You could also try sending your old board to QER repairs who repair boards.

Same thing I thought. I was upset they didn't mention it was not programmed. Others did mentioned they were not programmed, I assumed this one was.
I was thinking about changing the EEPROM over, but now found another site that says they can do an exchange on my old one. https://emwelec.co.uk I had contact them as it was not listed. So fingers cross and I would see how it goes from there.
Thanks
Yes that's another company dealing in repairing timers and modules.
If it was a new part and in original packaging and therefore resell-able you can send it back for a refund under the distance selling legislation within 14 days. You don't need a reason.

Thanks for the advice. I did return the other non programmed module back.
I got my original one repaired back from EMWELEC. They replaced a varistor and 4 other components. Plugged it all back up and still got the F11 fault code. My heart sank, it still was not draining.
Then though let me go over all the wiring. I took the connector back off from the module that links to the drain pump. tightened the pins inside them at both ens then made sure it was on firmly. Tried again and it worked at last, finally. I don't know if the wiring is at fault or connector pins.
The PCB module opened
Connector at PCB, two red wires come from drain pump on the 5 pin connector
Wires at back of drain pump
It might have been that the connections needed tweaking up after taking them on and off a few times? F11 is a different fault to what you had before (F09)?
