Hi folks, I am having a problem with my Alpha CB28 Combi.
When I run the shower, a manual mixer, the boiler fires up fine. It will stay alight for varying amounts of time and will turn off. It then fires back up again within about 10-15 secs.
Obviously during this interval the shower is then running cold until the boiler fires up again.
Sometimes if you leave the shower running for say 15 mins, the boiler will stay on and all is well.
The same thing happened last year, I changed thr Primary Temperature Sensor (PTS) & this sorted it out. So the first thing I changed was the PTS, but this time it did not work, unless I bought a faulty PTS. Any ideas, before I put a hammer to it.....
I also changed the DHW.
If anyone from Alpha reads this, can I just say this is the worst boiler I have ever bought, nothing but trouble from the start & Alpha as a company no help whats so ever. At least we have heating........
