Indesit WE 16 UK

[mrdeo]

Hi, I am hoping someone here can help me.
I have an Indesit WE 16 UK that refuses to run it’s program.

If I put it on a wash cycle and press start, the door locks, and then the clock slowly times down.

No error is ever given ;(

I didnt know what the red wire was on the pressure switch, but I disconnected the wires and found that the switch itself was appearing to work over the other 3 connection blocks (guessing the red wire is to change sensing level?)
I removed the door lock and found that when it’s energized the relay is closed.
The Sols for the water inlet checks out okay.

I reset the unit (no problem there)

I set it to “Drain” and it doesnt pump the water out.
Disconnecting the power line and checking, the pump (rated for 240) seems to only be getting fed 115 or so volts. I check’d across the relay on the circuit board and there wasnt a drop of voltage, I do hear an odd (single) click come from the pcb after it’s power’d for about 30 seconds.

all I have left is the heating coil, and the Motor.

I can see the mains making it to the PCB as expected..
It appears as tho when the door is engaged it just provides a more solid power rail to the pcb?

Test points on the PCB, Or any ideas to what is at fault would be of great assitance.

I dont really want to disconnect the motor, and the coils are submerged in water at the moment, but I can drain that if someone could provide me with the coil resistance (dont have a megger).

Regards
MrD

Probly motor brushes, JJ

Re: Indesit WE 16 UK

Should I be able to remove the motor completly, and the machine still pump dry?

I cant see there being a problem with it hurting the PCB to have no load, just not sure if the PCB would sense that the motor isnt there and refuse to operate. I havent tried this as I dont want the pcb to damage itself (unlikely I know, but wanted to ask)

(I have wired plenty of motors, not repaired many, but I could replace the brushes), Just hate to start spending money on something that might not be bad ;).

Re: Indesit WE 16 UK

You should be able to drain the machine by gravity if you put the outlet hose into a bucket at floor level. The heater resistance should be about 20 ohms but I would agree that motor brushes are a more likely cause than heater failure. Yes, if you unplug the motor the electronics will detect this as a fault and will not operate the rest of the machine.

Thanks.
I guess I’ll tear it down and see if they are worn out, It seemed to be running fine, no noise or sign of sparks :/..

I also wouldnt have expected the program to just stall if it was not requiring the motor /Edit/ Not doubting your word, just thinking of poor design /Edit/

Poor design :rolls: This is an Indesit machine we are talking about, 😉

Re: Indesit WE 16 UK

I get 30.1 ohm on the heater, a lot higher than 20 but I would still guess it’s in a normal range given what it is?..

The brushes are indeed worn, I wouldnt have expected it to drop off so suddenly however..

I can see the metallic strip in the middle, but one brush is quite dirty on the tip, the other one is fairly clean with stripes of the carbon (it is a carbon clay mix isnt it?).

Whent these brushes go (and I really cant understand why it would cause the unit to act like it does) does it run the risk of killing the operation of the board?

seems to be for the Indesco motors, but it doesnt list my washing machine model, guess I will email.

Re: Indesit WE 16 UK

Yes the heater resistance sounds OK. The figure I quoted was typical of washing machines rather than Indesits in particular so yours is probably a lower wattage than some others.
When fully worn there will be approximately 1/4″ of carbon brush protruding from the metal sleeve.

Hi

On Indesit machines the motor provides the neutral to the rest of the components. What normaly happens when the motormotor harness fails is that the door will lock but you get no indication and nothing else works.

Re: Indesit WE 16 UK

Hi guys, thanks for your help.

I went out and tried to find a new brush, but only one shop had something close, and it was for a C.E.Set? motor that goes on Indesits..
The packaging was exactly the same, The metal guide inside the pad looked the same, travel length and everything else all look’ed the same…

So I figgured I would give it a go :/..

Anyhow, The washing machine is now going just fine, I hope the part wont cause any harm :/

The replacement picture on the web from UKWG shows a different plastic housing than the one mine has too.. I have order’d a few times from UKWG but I needed a quick fix “Sorry guys” …

I sitll find it odd that the machine wouldnt operate (or at least flag an error) when that pad was worn down!..
