If you're going to do the job properly you should use a plug in relay (for easy replacement) and ensure the contacts are either Silver Tin Oxide AgSnO2 or the newer Silver Tin Indium Oxide (often shown as AgSnIn). Although controlled and limited, modern pump and boiler circuit boards can have...

Gotta be mad spending that much money on a car with zero warranty or legal rights. With starship millage what could go wrong :)

Those bricks are a pain to point.... You'd expect him to use a tuck pointer & hawk to fill the joints, then as the mortar has firmed up it's hit with a churn brush (stiff bristles) to remove any excess from the brick edges (without smearing) and finally the mortar can be compacted with the pointer.

He's making a mess of the brick edges Unless the mortar is exceptionally hard there are attachments that fit grinders specifically for raking out the joints.

He has absolutely no idea what he's doing. Pointing London Rustics is a faff but with the correct technique there is no reason to mark the bricks. I doubt he's even raked out the joints for new pointing to be effective...and what has been done seems random. Do not pay, he may issue a MCOL...

It's a heat pump dryer. Are you cleaning the moisture sensor and evaporator filter (behind the lower cover) on a regular basis ?

Indeed...recirc is on the blower. It looks like the blend actuator is a 5 wire type. 2 wires on one side of the connector will be the motor. The other 3 are the potentioneter with the wiper the centre wire. Straightforward to test with a multimeter.

If the blower is running on all speeds and the pollen filter is clean it sounds like the blending flap/actuator is faulty. Remove the trim panels to the left of the clutch/brake pedal and you should see the actuators and mechanisms for the temperature blending and vent distribution.

AFAIR that particular flue position is not shown on the building regs. or manufacturers diagrams. Gas-Safe tend to suggest we use our "engineering judgement" and of course the unscrupulous installers will not care less whether it's actually safe. It's possible a plume management kit might be...

The following (in no particular order) will sort most issues.... Most of the water sections I came across had the temperature and flow regulators but they were often seized and made little if any difference to the basic operation of the pin. However, unscrew the venturi and clean off any scale...

J&S specialise in warm air systems but got into combis in order to survive as the warm air market gradually becomes obsolete. They are a very low volume boiler manufacturer (with not a great reputation afair) and few engineers will want the hassle of dealing with them. That heat exchanger is a...

Low head F&E systems are often problematic and should be ditched in favour of sealed system...is the boiler not approved for sealed systems? There must have been a very good reason to not seal it. AAVs are plain trouble. Replace with manual vents...I use the 1/2 radiator type vent with a 1/2 BSP...

Unscrew the knurled ring first...then unscrew the square plug with the washer on the end.

I'd run it close to maximum...you don't want it condensing much given its age and parts availability. It's nearly 20 years old, unlikely to have ever had a proper service (and it's impossible to fully clean the recuperator due to the design and it could be very corroded by now) The sump gasket...

Great your're so optimistic but answer the question...
