Remeha 28c problem!

[Julieanneinspain]

The problem is still on going. We are having to switch the boiler off in between using the hot water. We are going to by-pass the rads when my brother has a spare day, and check all the pipe work for a blockage before I look at a PCB.

The df du values are still both 1, even after I have changed the parameters for propane firing.

I will speak to Remeha Spain later and see if they have an engineer in the area but as one place is 5 hours drive from here and the other 7 it seems doubtful.

Thank-you very much for everything.
I will post again if it gets fixed and let you know the problem.

Otherwise, I think I am looking at a Vailant!!!! Loads of engineers around here and a good 2 year full warranty!!!!

What is the value of Parameter 21 - pump speed? The default is 0 (low speed). It might be worth trying it on 1 (high speed).

have you checked that the divertor actuator is working? has it become unplugged?

I had an issue with CH not working and code '8'. It was due to a tap not being 100% closed so the diverter stayed in HW mode. Checked all the taps and CH worked again.
