Baxi Luna 24fi Flow Rate


Hi,

I have a Baxi Luna 24fi that's probably 12 years old. Was serviced about 4 months ago and was fine.

The heat works fine, but I'm having problems with the DHW (no hot water). I noticed if I turn on the washer set on hot, the unit ignites and works. If I then turn in the bathroom tap and shut off the washer, the unit continues to heat the water. I also noticed if I turn on the tap and shower, the unit will heat the water. However, turning only one tap will not activate the unit. From reading around, it sounds like a flow issue. Any ideas?

Your help is much appreciated.

Thanks,

Baxi Luna 24fi Flow Rate


The problem was the diaphragm. It was pretty much jello. Replaced the entire casting and works fine.
