Re: Neff D/W (E19 error) S51M66X0GB/B1 (Fd 9507)
Error E19 still present after replacing heatpump.
Do these machines have an error reset proceedure?
I am ready to give up and let neff take over
Re: Neff D/W (E19 error) S51M66X0GB/B1 (Fd 9507)
Dump valve Solenoid isnt open circuit though? I even tested from the control terminal through the wiring.
I messaged Bosch and they are suggesting a possible heatpump fault. Which is handy as i have one of those on order for another job which i can briefly hook on to see..
Thanks for the reply, though
Appreciate the help.Re: Neff D/W (E19 error) S51M66X0GB/B1 (Fd 9507)
Still no further forward with this one. I returned today to double check the things i tested first visit.
I can only assume the control module is faulty.
The E19 error is present a second or two after the machine is switched on.
It briefly flashes the program length (2.15 etc) but immediately changes to E19.
Cant reset the fault or get the machine to do anything.
Re: miele cond dryer T8822c "clean out airways" after 20 m
Worked on an t8442c recently, dif fault. But might be worthchecking the thread (week or two old) as i posted the thermal sensor reading charts. Temp/kOhms.
Possibly one of these reading too hot, thus machine thinks its airways are blocked?
There are some links to various manulas of similar machines tbere too.

Re: Samsung WF90F5E3U4WEU stopped 10 mins
Have you tested whether the element gets a live feed? Often the relay switches the neutral and as such the live still gets to the element.
Dont quote me on that though, just something I would check…
Also, worth cross referencing the kOhms of the thermal sensor?
Re: Neff single oven door issue
Whats the model number?
From my experience, the doors are designed to ‘snap shut’ aren’t they? Maybe the old hinges had deteriated and the customer has gotten used to faulty hinges?
Re: Miele T8422C Tumbe dryer | Cool Down light and Buzzer Fa
Hello guys.
Just a quick summary for the benefit of anyone reading this thread in the future.
Renewing the relay which activates the neutral cured the fault. Whith a new relay the machine heated as normal.
Although the relay didnt show any visual signs
of damage, when i desoldered it i notice on of the legs dettacthed. Possibly a result of my man handling.Glgl
Re: Senor meile dyer
Have a look here my friend:
Derived from this manual:
Re: Miele T8422C Tumbe dryer | Cool Down light and Buzzer Fa
Regard the thermal sensor located under the door. Here are the respective readings:
Again, this corresponds with the values I tested (13KOhms = 22’C ish)
So, it looks like both sensors are working correctly. This leaves me to deduce the fault is in fact on the relay board. Specifically, the relay which switches the Neutral to complete the element circuits.
Cheers.
Re: Miele T8422C Tumbe dryer | Cool Down light and Buzzer Fa
According to this manual:
https://www.manualslib.com/manual/83192 … =32#manual
Which is for a Miele model T9800…
[Edit – I think the sensor in the element box is actually an 1R30, its one or the other!] The R230 thermal sensor (which is located in the element housing) should have resistance readings as outlined in attacchement…

Customer was intouch today saying they will make payment by end of the day. Fingers crossed, although that’s now the 5th time I have heard this 😀
Thanks for your reply.

The drum moisture brushes were fine.
The thermal limiter on element box is good.
No visible signs of damage on the Element relay PCB, however, at no point did the element ever get a Neutral. The Left most Relay (when looking at relay pcb from above) never allowed the Neutral through to complete the circuit and as such the machine never heated.
That’s either because the Relay is faulty, or the sensors are preventing the relay control circuit from activating? Is that correct thinking?
Now I understand it, i think!
The Sensor probe located in the element box read: 138kOhms
The probe located under the door read: 13kOhmsThese readings were at room temperature and both probes lowered their resistance when i warmed them with my fingers.
Can I ask if anyone know’s what kOhms these probes should be reading when working correctly at room temp?
Thanks.

Now I do feel silly!
Thanks for the hedas up Dave.
Re: Senor meile dyer
Was planning to desolder and swap the relays – the element relays did allow voltage through. But the circuit was never completed as the neutral relay didn’t switch – alas, trying to hold the board whilst applying the iron AND trying to prize the relay away was impossible.
It’s so awkward when the relays have 4 legs right close to each other. By the time you get the solder melted and start pricing the relay away, the other legs have cooled down and nothing budges.
Infuriating tbh.
I’m trying to find what the sensors (kohms) should be rated, but finding nothing.
Sigh!
