Boiler not staying on

[Craigi1990]

Pump has arrived, I will fit this evening after work.

As its out I might aswell change the washers in there. Are they all the same for Central heating pumps?

I. E will these ones do?

Rubber type gaskets are normally supplied with any pump, don't like the fiber type as can eventually leak/draw in air.

Is it another Alpha 2L you purchased?.

Yes,

I'll be honest, I bought a reconditioned one for now. There is potential that it will be switched to a combi in the next year or so. I just don't have the cash right now to do that

Just swap the head then 4 Allen bolts and done

I have the other one off already completely already.

The electronics on this one are very slightly different. It has a self vent button on.

Just to conclude incase it can help anyone in need in the future. It all seems to be up and running now. Boiler been on 10 minutes. Pump is clearly moving water. 3 port is working as it should be.

So it does seem to have been the pump had died.

Thanks for everybody's advice.

As a matter of interest, what mode/speed have you set the pump to?.

I have it set at 4. 3 Only tends to warm the furthest radiator in the living room. 4 is needed to actually keep it hot. Been that way for the 5 years I've been here.

If its 4 presses of the button then that appears to be constant speed 2, (3M), which LED is illuminated?.

Also good to see you are able to get a reconditioned unit as mechanically, bearings etc these should easily give a life of 10/15 years, seems a shame to throw them away after 5 years or so if the electronics can be replaced. A few Dab Evosta 4-7M pumps around here are still running away after > 8 years.

4th light on. 7 presses? The maximum it will go I think.

4th LED on from the left is PP1( 6 presses?) which is only 2M reducing which IMO is far too low for the whole system.
5th LED on from the left is PP2( 7 presses?) which is 3M reducing and if this is where its set to and your system is happy then OK but if not I would suggest 6th LED from the left (1 press?) CP1 which is a constant 3M and should satisfy most of your needs.
