JLWM1437 (Electrolux) Direct Driver Inverter W/M – Slow Spin Speed

[pearce_jj]

Hi, hoping for some help.

Washer is working normally (quite and stable) except that the spin speed seems to be reduced to only 300rpm (top speed should be 1,600rpm).

Drum feels smooth, turns literally silently. Pump cleaned. No errors displayed, it just reaches the lower speed and that’s it.

I’m wondering if the inverter board might need replacing.

To add. The other thing that’s changed is that if a wash is paused, the door doesn’t unlock. Maybe there is a water level sensor that needs cleaning or replacing?

Are you putting a full load in?
This problem can be caused by under/over loading the machine.

Thanks for reply. Same even when machine empty.

Also, I ran a 90* wash but it doesn’t appear to be heating the water at all.

check the heater
if heater has gone it may be the total problem and odd earth faults on heaters can cause problems

Thanks. Heater is 31 Ohms and the NTC sensor reads 6k at about 20*C.

Ive been trying to get into diagnostic mode but so far without any luck.

For the benefit of the search. JLWM1437 service/diagnostic mode is the same as AEG 6000/7000/8000/9000. To access, turn off machine at wall. Set dial to Cotton. Turn on machine at wall. Turn on machine with on/off button if it hasn’t come on itself. Touch and hold “Start” and “Reduce Time” for about 3 seconds. Screen will display test (every segment lit). Then rotate dial to desired test program (see YouTube). Any errors will be shown. Power cycle machine twice to exit diagnostic mode.

Last error can also be shown on-screen at any time by touching and holding the same buttons.

In this case it’s showed E62 (overheating) and, on every test program, E71 (faulty NTC) – so I’ll give a new temperature sensor a go first.

Error codes are documented here.

Exploded parts diagram is available via Electrolux here, which gives part numbers for use elsewhere as well.

cant find values for ntc but it does not look too far out

E71 fault is listed as short or open circuit ntc

check the wiring before you jump in and buy one

Thanks, will check!

[USER=”4209″]electrofix[/USER] – thanks, it was indeed wiring. One of the sensor cables was literally snapped at the point where the wires bend as the drum moves about.

Cable spliced and machine is heating and spinning on the test programs, hopefully that’s sorted.
