Yeah a good shout, but like you said I am thinking maybe someone has tampered with a gate valve somewhere or another...... although the customers swears blind they haven’t.... the weird thing is I went to the property 5 days ago as 1 radiator wasn’t working, I released the trv pin and it warmed up immediately!!!!
I pulled the magna clean pushfit fittings off and checked to see the valve open and close
Don’t understand sorry

Arnt them valves on the boiler closed I’ve had a few where the handles round and don’t do anything

Think he means cut f & r coming off boiler and loop them to see if that alone heats. If it doesn’t it’s inside the boiler
Removed both valves and checked they were both open

cut into the flow & return low down and link them together to make a very small circuit. If the link doesn't get warm then the blockage is in the boiler.

But that wouldn't explain why he's getting no water through the bottom valve leading to the magna clean.
Exactly....... Accrington Stanley lol

Oh yeah forgot about that. Got to be a blockage in the system then. Most likely where Craig said in that elbow with the red ring round it.

Think you said you'd already done few bits of this but I'd approach that job in following way.
First walk the system and see if there's any valves on the ch circuit anywhere that could of been switched off in error (sometimes where it was a conventional boiler with cylinder in airing cupboard valves get left in e.g. Summer valve)
From there I'd drain the boiler and remove the 2 isolation valves and ensure they are 100% opening and that they opening all the way.
Then I'd follow the magnclean valves the same which again I think you've done.
If possible to identify last rad on return to boiler. Isolate and drain. Then attach hose or just into a rubble bag open the return side valve and see if you get the correct flow of water coming out. If yes then the fault definitely lies between the magnclean valve point and the return of the last rad.
Once identified there's a few options.
With system drained connect into the pipe at magnaclean pipe with a 22mm compression fitting (in place of the bottom magnaclean valve) going down to an 8mm copper pipe (or appropriate fitting made up to fit a footpump up to... 8mm pipe works perfect if you've got some.)
Then pump up the pressure and it can clear by pumping up to a high pressure. Obviously there is a risk with this... But generally the risk is a joint popping and needing re-piping. . But that's one of the other options anyway so I'd try this first after checking all accessible sections of pipework.

This post beggars belief, unless I have missed something, no water is getting through the magna clean valve. ,!!!!! Start there .

Aire
He said he's checked it
Both magna clean isolation valves do open...... the pictures shows the top valve closed, when opened water be flows out of the magna clean, the bottom valve is in the open position and actually opened but no water flows out.... I have checked it with the magna cleaned removed ....
No I haven’t great shout, will do that tomorrow.

Why not using a wet vac once you took the filter of the nuts? You could leave the top one closed bottom one open and and try sucking out. Once water is coming close off and re install the filter.

Are the flow and return iso’s Pointing towards you?
No pointing upwards, they have been removed and checked to be in the open position...... zzzzzzzzzz sleep time

On an Ideal I thought that they had to be pointing towards you for flow to be achieved?

Hey did they come out yet? Could the diverted body inside be jammed to dhw? Therefore stopping flow round heating circuit?
I was thinking that but I removed the DV motor and manually pushed in the pin fully but still no different....... the customer is not prepared to call out Ideal so we may never know?????

Oh well if customer isnt bothered then they will call someone else (if not you) when it gets cold again
True but if someone repairs the boiler then I will never know what was the problem and would have spent a lot of time for nothing ..
Will never know the customer got another plumber in who replaced her boiler.... all that work checking valves on magna and boiler all for nothing, it’s not getting paid that’s the pain it’s not knowing what the fault was

Do you not charge for fault finding?
I do but on this occasion as I was not 100% sure what the fault was I didn’t....... I don’t have a call out charge I have a diagnostic charge. If I don’t the fault there is no charge
