No hot water from my alpha cb24x?

they are ripping you off parts and labour should be no more then £80 - £100

I unclipped the flowswitch, tested it by pressing and releasing the switch. I then made sure that the flowswitch was pushed fully into its holder. All works OK now.

You can buy a flowswitch from:

I think this is a bit dear so I am just going to try to buy the switch from CPC rather than the holder as well.

Plumbers are a rip-off. £300-00 to replace a switch?? I don't think so.

ive had the same problem . its the hot water flow switch . undo the 2 screws in the front panel . (drops down ). the switch is located on the main valve (black plastic ). it clips around the valve . using two small screw drivers i stripped and cleaned it up . checked with a multimeter. ok then refitted . boiler works all ok now ...
just be carefull with the switch as its quite fragile ...

Hi we also have the same problem with our alphaCB24X. We were advised by a plumber to buy a new boiler rather than pay so much for a tiny component

I had the same problem. The hot water flow switch contacts had gone. I can't believe it will cost £300 pounds to fix. It is a small job - simply the replacement of a small (but special shaped) microswitch.

i have the same boiler as you with same problems but i am doing a house extension so i have to upgrade to a new system anyway but the plumber told me its a diaphram in the boiler that could be the problem he said he put the pressure up in the boiler which was up above the green a good bit and this would help until you get it fixed but he said you are looking at £300 to £400 to fix it,so you will be better getting anothe boiler etc glowworm / vokera with a 2 year garentee a straight replacement old boiler out and new one in hope this helps.
