I have a sime 100e that does not give hot water only tepid. The central heating seems to work but with the water thermostat at max it is only look warm.Can anyone help please?
Just had the same problem, it was the diapham for the hot water switch, diapham had perished, system is 6 years old. cost was £31 for part. It's very awkward to do but possible, you need to remove the switch by pulling out the clip then remove the 8 bolts on the housing of the diaphram. it is very awkward to get screwdrivers in, I managed it with offset screwdriver. The housing pulls down from the connection above, please be aware which way the diaphram goes back in
