BAXI COMBI 105e..... HOT WATER BUT NOT TO RADS

Engineer checked for blockage in filter..seems ok...

Fitted DiverterValve Unit....Still No Hot Water to Rads...
Drained system & refilled....
Still NO Hot Water to Rads...
Any ideas would be appreciated...Thanx

Domestic hot Water Fine..
But CH fires up Hits 80C in 5 secs & trips out until temp drops to min 30C & then fires up again(3 mins later approx) then hits 80C in 5 secs...trips.... & repeats this cycle???

Ch heating thermistor mate, its a £3 part which you can change yourself and if (when) it works insist that your divertor is changed back and do not pay for a bad repair job.

How easy is it to fit this "Thermistor" ??? & where is it located on boiler.
Many Thanx :D

It a little plug with a wire to it on the flow, its dry (no drain down needed) and will come out with a 13mm spanner

Are the flow switches ch and dhw on there correct diffs ?
 
ChrisR...I would consult manual if I had one..
when I did source and consult an online manual a thermister is not mentioned anywhere.
But consulting my crystal Ball I now see that a Temperature Sensor is actually a Thermister ...

and low and behold I can now locate the little fella....

But Thanx for your input anyhow !

Im in Preston
