Re: Hoover washing machine overheats
adamhornsby wrote:Back to main problem about the Hoover, does anyone know what is happening with it,
The thread has gone so seriously ‘off topic’ I’ve almost forgotten what your problem is? 😕
“Overheating” eh? Whilst you may have done a continuity test of the thermostat it doesn’t in fact have one of those but a Thermistor instead. Now the cheapest option at this stage would be to replace that, especially (by pressing the prewash button- If I recall correctly?) if reducing the pre-set temperature fails to change anything?
“Going on without ending” is a little more of a worrying as that could be a fault with the TMX Slave Unit? And if, when it plays up, it doesn’t show an Error Code on the LED Display panel, then likely as not the TMX unit and the Control Module will be at fault I reckon?
Start with replacing the Thermistor I would and check you have full continuity from that right back to the module board connection. (duff connections can be a bugger to suss after all?)
Hope that helps?
Re: Hoover washing machine overheats
The original “New Waves” did not have any Error Code numbering; that only came with the ‘hybrid’ boards.
The usual result of an error/timeout, was to pump out, and for all LEDs to flash in unison.
Re: Hoover washing machine overheats
Yes, Trilobite, the machine before has had all the lights flashing before, where it would end in the middle of the cycle, but not while its had this overheating problem.
Re: Hoover washing machine overheats
The only things that I can think of are:
a. The heater relay contacts are welded in the ‘on’ position, due to the current required to power the heater. Relay failure is common to all makes and models.
b. Somehow the programming has become corrupted. This could be from the motor brushes sparking/arcing, or from a poor contact on the wiring loom. Apparently the programming was ‘hard-wired’, so there is no facility for replacing an EPROM chip, like other manufacturers offer.
I have read that the A.B. Electronics sourced boards fitted to the New Waves, were troublesome devils. I would seriously consider a new machine. You will be surprised by the quietness of new ones, compared to the New Wave.
Re: Hoover washing machine overheats
We’ve already replaced the heating element as one of the ends had corroded, but still didnt make any difference. The only thing we haven’t looked at is the timer, the big thing at the right hand bottom corner at the front i think. Yes Trilobite, it is a noisy lump, both when washing and spinning, it sounds like a helicopters landing on the roof, but hopefully the Miele will eventually sort that out.

Explain on the temperature changing thing please, as i never knew you could do this.
Re: Hoover washing machine overheats
On the early ‘New Waves’, the temperatures were pre-set. You could reduce the individual wash temperatures by about 10 degrees Celsius by pressing the ‘Economy’ button. There was no actual temperature indication.
Thus, programme #2 (Fast Coloureds at 60 deg C.), would become 50 degrees, on pressing the ‘Economy’ button.
I think later (hybrid controller) models, had a fully variable temperature option. So if you chose Programme #2, you could lower the temp by repeatedly pressing the ‘Economy’ button: 60,50,40,30, etc. The temp was displayed in the display window.
Re: Hoover washing machine overheats
overheats on a 40 degree wash, so temperature reduction won’t exactly work, but we’ll give it a try. If the timer was the problem, how much would it be to replace?
Re: Hoover washing machine overheats
When my mother’s machine started playing up big time in 1999, the parts were going to cost £180 or more. It really wasn’t worth it. When I had a look at it, the power board had arced at the motor wiring-loom connector.
The machine had previously developed an erratic spin profile, and would abort its programming (during the wash) every other day. The end was nigh when it did it 4 times in succession.
Re: Hoover washing machine overheats
Okie dokie, the machine ’tis getting worse! On one of the cycles that previously worked, the number 7 Woolens, overheated, drained and stopped halfway though the cycle with all the lights flashing in unison, with every program apart from the cool and quick washes getting too hot, it will soon be a matter of time, before these go faulty too.
‘Tis absolutely rubbish ’tis Hoover!Anyone, please help.

your previous post said it lasted 15 years not bad for 4 of us.
‘Tis Hoover ’tis 15 years old ’tis lasted a lot longer than most of the cr@p available today.Re: Hoover washing machine overheats
Well, yeh, that is true, but that doesn’t help us fix it despite us not even knowing whats wrong with it.
Re: Hoover washing machine overheats
i dont really like people slagging off hoover and then asking for help, but i will give you the benefit of the doubt, i am hoovers biggest fan but i think the new wave was one of their less reliable machines, the big pcb in the bottom front rh side as you look at the door is faulty.
take it off and check for dry joints in the solder or blown tracks, again if i was honest i would not fit a new pcb to a machine that age.
before you replace the machine take a good look at the new range of hoover washing machines available in 6kg, 7kg or 8kg load sizes.
the 7 is the best i would not recommend the 8.
they are reasonably priced, come with a 5 years parts guarantee, and are good value for money, they are also easy to repair.
