KevinWhiteJA :

Hi, welcome to Just answer

KevinWhiteJA :

How old is it ?

JACUSTOMER-adsnphdx- :

newish just out of warranty

KevinWhiteJA :

OK, as it is blowing cold air the problem is with the thermostat that is bad and will need replacement

KevinWhiteJA :

however, if you take the back off the unit there is reset button on the thermostat

JACUSTOMER-adsnphdx- :

ok how do i replace?

KevinWhiteJA :

just press it and see if it works again

JACUSTOMER-adsnphdx- :

to take the back off does nt seem to be as easy as other machines do i need to take the blow tunnel off, then the back panel behind that

KevinWhiteJA :

just the small one

KevinWhiteJA :

I mean the one that is in shape of belt

KevinWhiteJA :

if you remove that...there is a thermostat with a reset button on it

JACUSTOMER-adsnphdx- :

there is the metal 1 which when removed all you see is the blower and nothing else there is a little plastic 1 which when removed there is a coil

KevinWhiteJA :

if you are talking about the heater coil then the thermostat should be near that unit

JACUSTOMER-adsnphdx- :

this machine is the bosch self cleaning type wtw863s1gb

KevinWhiteJA :

OK, if the reset is not there then can you test the heating element and thermostat located inside the back for continuity with a multimeter

JACUSTOMER-adsnphdx- :

found the trip but its not tripped

KevinWhiteJA :

and still you have tried resetting it ?

JACUSTOMER-adsnphdx- :

yes

KevinWhiteJA :

ok, can you test them with a multi meter for continuity

JACUSTOMER-adsnphdx- :

i'll need to get a multi meter what am i looking for

KevinWhiteJA :

there are two thermostats located inside the back and a heating element

KevinWhiteJA :

usually the heating element assembly is replaced

KevinWhiteJA :

you can test these parts for continuity

KevinWhiteJA :

no continuity means bad element and will need replacement

KevinWhiteJA :

the element assembly includes the thermostat and a new one will cost around £60

JACUSTOMER-adsnphdx- :

where can i get a replacement part

JACUSTOMER-adsnphdx- :

is the element the part where the trip is

KevinWhiteJA :

You can get parts here

KevinWhiteJA :

yes

KevinWhiteJA :

You can get back to me if you need any assistance and I will help with no additional charges

KevinWhiteJA :

Is there anything else I can assist you with today ?

JACUSTOMER-adsnphdx- :

the multi meter reading across the coil is 109.3

KevinWhiteJA :

OK, I hope you set the meter to its lowest setting and then checked it ?

JACUSTOMER-adsnphdx- :

200

KevinWhiteJA :

and the element was removed when you have checked it ?

KevinWhiteJA :

set it to its lowest setting please

JACUSTOMER-adsnphdx- :

when you say element removed i' checking the coil where the trip is,

KevinWhiteJA :

ok

JACUSTOMER-adsnphdx- :

if you go onto the bosch parts site its number 0512 is this the correct part

KevinWhiteJA :

sorry for the long pause

KevinWhiteJA :

was checking all the diagrams there

KevinWhiteJA :

yes that it is the part

JACUSTOMER-adsnphdx- :

just to clarify we have set the multi meter to 200 the readibng is 109.3(what should it be?), teh motor is working and the compressor is blowing cold air so is this the part thats breacking down or is it the thermostat?

KevinWhiteJA :

The meter should be set to its lowest setting not at 200 ...if the dryer blows cold air usually the problem is with the thermostat that is bad and will need replacement

JACUSTOMER-adsnphdx- :

the lowest multi meter ohms setting is 200 we're getting a reading of 109.3, the thermostat is only £5 rather than £50 for the element, which 1 do you think needs replacing if any

KevinWhiteJA :

I still believe it is the thermostat

JACUSTOMER-adsnphdx- :

is this part number 0527, sorry to be a pain but want to order the right part

JACUSTOMER-adsnphdx- :

also how do we get to the part to replace?thanks

KevinWhiteJA :

Yes that is located inside the rear panel to the exhaust duct..
