Baxi 105e No Hot Water

[chrisk69]

I have a Baxi 105e Combi but i am now not getting hot water.
The central heating works perfectly, but when i turn the tap on for hot water, the boiler will not fire and the green neon light over the tap icon flashes.
Does anyone out there know what the cause of this is.


Please Help as I hate cold showers..........

Many Thanks

Chris.

Is it an 105e 'Instant' by any chance?

I'm not sure if it is a 105e Instant i have lost all books to the boiler.
Will it say the model on the boiler somewhere

your need a new dhw diff flow switch

pre heat is on when green light flashes

For parts and instructions

You need a 248731
or just the diaphragm 248838 (Diaphragm - DHW/DIFF - Instant )

.. or just the microswitch?

 

[baxpoti]

The 'Instant' micro switches are very reliable

Thank You All for your input and help.

I think i will remove the diaphram first from my boiler to check it, as this is clearly the cheapest part to replace first.

I will keep you updated on my progress to let you know who was right.

Cheers all

Speak to you soon...............................
