Help/advice Baxi 105e

PAULIEJ

I bled the radiators on this system as they were not fully warming up.The next morning the timer didn,t kick in so no hot water or central heating!!! The boiler is displaying a fault-problem with pump or pressure, and the pressure bar is down to zero.The pump is also making a bit of a racket when you try to turn the water or heating on.What the hell have I done and can it be cured?Is it just a problem with the pressure? Many thanks for any info or advice.

:mad: :beer: :T

as you bled system there is not enough pressure/ water in radiators

there should be a silver pipe called a filling loop

open it and look at guage

close at about 1.5 or in green

Just fixed my Baxi 105e after reading various messages on this and other forums.

This is the fourth different problem with this crap bolier in 13 months, mind you it is 6 years old now.

I just stopped getting hot water overnight, there was no problem with the central heating and also there were no fault LEDs showing.

When you turn the tap on a little plunger should come out of the diaphragm and push the micro switch to make the hot water LED come on and start heating the hot water. This stopped working, the fault was the circular rubber diaphragm, about 3inch diameter and ~£10, was perished.

It is really easy to change, just remove the small pipe going into the top of the diaphragm and then the 8 screws at the front. Make sure you fit the rubber thing in the correct way and reassemble everything in reverse order to dismantling it.

Hope this helps!


For reference the other problems I have had:

The 80degC LED was flashing, this turned out to be the central heating temperature sensor, ~£14 and you do not need to drain the system.

The 70degC LED was flashing, this turned out to be the hot water temperature sensor, ~£14 and just turn off the mains water tap.

Everything stopped, this was the main PCB, it was easy to change and cost £96.
