I removed the pump and heat exchanger yesterday and they were both clear and not blocked. I then realised that it was the pump that was failing and was intermittently working and sometimes not running at full strength. I picked up a new pump head from the wholesalers today and fitted it this...

Thanks Gasguru. The CH which wasn't working, is now working. The fault is intermittent. Sometimes the pin rises and sometimes it doesn't. Sometimes the pin recedes and sometimes it doesn't. I think that poor flow is the answer but whether it's the pump or the heat exchanger is tomorrows...

Not anymore. Just back home and the CH has stopped working now.

Yes. From what I can gather the pin is up for DHW and down for CH. Thanks

Thanks guys @paulthegas. It is an on going fault. The hot water is intermittent. It works correctly occasionally. Sometimes it locks out the boiler and it needs resetting by switching off and then switching on using the control knob on the front of the panel. Note it wont reset by pushing the...

Hi paulthegas It is listed in the manual as the CH micro switch. What I don't get though is why the top of the diaphragm is wet. There are no holes in it as it's new and when I remove the housing there is a lot of water on top. However in the picture below on the right hand side of the...

Hi twgas The pin which switches the micro switch is clean and moving freely. When the tap is turned off the water stops and the boiler 'clicks' right away. I decided to strip down the diverter valve to clean it out. I managed to get the left hand nut off the end and get the spring and spindle...

Hi all I am still having problems with the Halstead Finest Platinum combi boiler. I found the problems related to the DHW flow switch operation and was advised to replace the diaphragm. I got a new one and have replaced it but I am still having problems with the pin pushing out too far and not...

So, what causes the boiler to stop working when the water pressure drops? Also, as for your assumption, I didn't buy the boiler I inherited it when I bought the house.

Hi all I have a Halstead Platinum Finest boiler which has developed an intermittent fault. When it goes into fault the DHW and CH both stop working and when I push the reset button for >3 secs, I get the fault code for low water pressure. The water pressure is 1.2 bar and the gauge is working...

Thanks. I have a rad in the bathroom to change for a towel rail and a rad in the kitchen to move and then the system will get a dose of inhibitor. Although I have to say when I drained the system I was presently surprised to find the water running clear. :)

I took out the hose this morning and cleaned it out. It wasn't easy. It was choked up and the sediment had dried out hard. But I got it cleared and refilled the system and the system is working perfectly. Many thanks for your help 'ianmcd' :D

Thanks, I'll give that a go at the end of the week.

Aprox 2 minutes

How has it gone? I have checked it for water and have re pressurised it twice and it holds the charge. What else do I look for?
