Boiler still not repaired. Help

hora

We have a Glow Worm Betacom 30c boiler. 

About two weeks ago the boiler was losing pressure over night so we had to top up. 

Then the radiator/heating wasn't heating up. Just turning over. 

Insurance company (boiler cover) sent an Engineer.  He fitted a new PRV and a electrode (right one of the 3).

He left before testing it worked. 

No heating or hot water. 

Then the heating/started working on their own but with the same leak. 

He came back and said it was the pipe that leads from the expansion tank to the PRV. Changed this and now we have hot water but no heating. 

The hot water is red hot. When you select heating the LEDs light up then die down quickly to the boiler just ticking over again. 

Another engineer has come out and said he thinks its the pump (it works when hot water is running but doesn't turn when heating selected). 

He said he checked the diverter valve and mechanised diverter actuator and doesn't think its that. 

The clip doesn't seem to click over though when you select the heating. 

The insurance company think they have done their part up until the pipe being fitted as they state that their terms and conditions only cover us for 3 hours labour and a set amount of parts. Immaterial that they haven't actually fixed the problem. 

The final Engineer said he could guarantee that it is the pump and if he is wrong he will only charge us the labour and remove the pump that he fitted. I didn't ask him/prompt him to say this. 

That means if he is wrong we have to pay 2+hrs for the mistaken belief. 

We just want our boiler working. We are now in a worse situation than before we engaged their engineers 

We don't want to start throwing money at the problem with the hope that a part will eventually come across the issue. 

Thoughts?

This is Oil and LPG section .

Employ a local guy with a decent reputation .

Pump is a known problem on many systems ,but not 100% the problem .

Insurance reads as you have got what the policy gives you  in xxx hours labour .

The insurance company think they have done their part up until the pipe being fitted as they state that their terms and conditions only cover us for 3 hours labour and a set amount of parts.

Is that what it says?

Is that what you've received?

Many boiler company policies have limited cover. You get what you pay for.

Either get them back and pay them, or find a local independant engineer.

Employ a decent independent local RGI who can do fault-finding by diagnosis, rather than just swapping parts and hoping.
As for his offer 'to only charge you the labour' if he's wrong, I wouldn't want him near the boiler.

Don't Glow-Worm offer their own fixed price repair service?  Maybe not the cheapest option, though might be worth considering as you'd hope they'd sort the problem.  Check the Ts and Cs though, IIRC there are a few parts they charge extra for.
