Hi Andrew,
Just wanted to say a huge thank-you!!!
I've just replaced the sensor and have hot water again :)
The old sensor gave a reading of 1.8 where the new one was indeed within a hairs breadth of 12. It shows signs of very slight water seepage so I've made sure to clean up the mating...
Hi All,
I have a Potterton Promax Combi HE Plus combi boiler. It was fitted when the house was built about 4 years ago and has been fine until this morning.
I was only able to get a useable temperature for a shower by turning the shower temp to the max position and even then it was lukewarm...
