the water in my machine does not get hot, i have bought
1 new water heater
2, new thermostat
3, new electronic control panel
4, new water level sensor
the new control panel has jumper settings which we believe to
be set up correctly, does any body have any ideas why it is not heating up,
the water heater cables are fine one had to be cut back due to it being cooked. please help as this problem is driving me nuts. its probably something stupid and simple if you know about such things. Can i get any technical info on this from anywhere or a book i can buy to help in fault diagnosis, or just some advice, regards and thanks in advance.Re: WFO2866GB/01 No Hot Water!
Blimey! Seems you’ve replaced most everything you could here? Must have cost you a small fortune? 😯
Was the Heater actually faulty or did you just change it without carring out a multimeter test on it? 😕
Are you not getting any error flashing LED’s and/or an error code on the LCD unit?
Re: WFO2866GB/01 No Hot Water!
No error codes nothing, the machine works fine, it just does not get hot on any program, there is no power going to the heating element
Re: WFO2866GB/01 No Hot Water!
there is 8 ohms on the thermostat
and the heating element goes to zero ohmsRe: WFO2866GB/01 No Hot Water!

By “thermostat” are you referring to the ‘Thermistor’ that pushes into the front of the Heating Element? Because that should not give you a reading of 8ohms in situ!
Re: Bosch WFO2866GB/01 No Hot Water!
this part is new, what should the reading be & would this tell the control panel not so send power to the water heater, regards steven
Re: Bosch WFO2866GB/01 No Hot Water!
NTC or thermistor should read 2-4kOhms at room temperature, when split from the circuit. Resistance declines with temperature – a reading in ohms only would tell the computer that the water is hot already.
Heater should give a reading of 20-30ohms.
As these are parts you have ordered, you should have received 265961 – heater, and 170961 – NTC sensor.
HTH,

thanks for that, so why wouldnt there be any power going to the water heater, i am baffled?
Re: Bosch WFO2866GB/01 No Hot Water!
Think about what I said – a reading from the ntc in ohms represents hot water to the computer. If it thinks the water is hot enough, why should it turn the heater on?

Re: Bosch WFO2866GB/01 No Hot Water!
Sorry for sounding stupid but problem has been doing my head in, I can’t think straight.
Re: Bosch WFO2866GB/01 No Hot Water!
If i unplugged the ntc for a short while would this let the water heat up
Re: Bosch WFO2866GB/01 No Hot Water!
Doubt it, just dug up the following bit of tech info:
“The NTC operating range is between –5 °C and 103 °C. If the NTC value is outside the operating range (e.g. interruption or short-circuit), the programme continues cold without an error display”So, time for an NTC sensor, me thinks. Concerned that heater reads 0ohms though……

Re: Bosch WFO2866GB/01 No Hot Water!
Hi
Heater should read approx 20-30 Ohms.
If you are struggling and have already spent on parts, it may be time for pro help? 🙂
Unplugging NTC would result in wash action as normal (without heat) to the end of cycle IIRCGreg
Re: Bosch WFO2866GB/01 No Hot Water!
Hi there, the heating element reads 0 ohms when i put my multimeter on the connections when the machine is switched off,
the element is new from boschthe ntc reads 8 ohms in situ when the machine is switched off in situ, the ntc is also new from bosch,
the machine does work fine otherwise, just no damn heat.
I thought that when you put a multimeter across the terminals on both parts, if it whent to 0 ohms that it meant there was resistance meaning that there was no break in the circuit in both parts, thanks so far for your advice it has been so much help.
