Baxi 105e no heating ect

[Strangey]

Hi I have a Baxi 105e around 1 week ago my DHW stooped but the heating was on top form having looked at the boiler it stated that the DHW sensor needed replacing , This was done last night since then i have no heating and my water is Luke warm never going above 50 i was advised to replace the diaphragm this was done and still no hot water or heating.

In brief when hot water is called for the gas fires up but only heats it to luke warm, when heating is called for nothing happens, lights on the front are red 30 and 40 on constant not flashing green lights on radiator icon.
When i listen to the boiler it clicks as if it is trying to fire up.

Some advice would help please

When the work was done, were the two microswitches on the diverter valve replaced in the correct positions?

Yeah as i did it every thing was replaced as it was with the old diaphragm.

Hi well i thought all was well how wrong was i.

i realised that when the radiator gauge was on full it was actually overiding the on and off switch ???along with no DHW.

This morning i have figured some way of getting both heat and water but still want help please as now i need to turn the boiler temperature for the radiator to half way this enables the radiator to work by a timer (if the dial is moved slightly up it just overides the timer and stay on constant) as long as the radiator gauge on the boiler is set to half way the DHW reaches 60 degrees. so i know it is not correct but i am gettin there so if some one can help please post as i am not sure how long this will last
