Come on now all boilers have problems yeah it took a long time but have you seen the brand new isar and icos leaving the factors ? nice metal components v9 more reliable boards and alot of revisons from the early models. Heck if u want to boiler bash how about viessmen the eu pioneer of...

It would sound like a blocked or scaled heat exchanger. If you have your manual grab it and look for the Domestic Hot water plate heat exchanger. Once u know where in the boiler it is place if safe to do so a finger or hand on it on hot water mode, if its red hot and hot water is hot cold...

the main heat exchanger lol i done them a few times what normaly happens is they pinhole and are not a 5min job to change, as they are a push fit n clip needing the fan ect removed. From experience if one goes it will take out the h/e of course most of the combustion panels maybe the pcb if...

It would be the flow rate through the shower unit. The boiler is designed on average to have at least 4 l/m to activate the flow switch. it could be blocked. Try this jst to give your self an idea of the problem turn shower on fully for hot water, turn the bath hot tap on and see if the...

It's been a while since i was with BG as a engi (what a mistake) but yeah the price is about right for them i believe it was something like 65quid an hour plus vat don't know if its gone up or down.

http://www.knh.org.uk/knh/publications/pdf/centralheating/rwb9daily.pdf for your clock i dont have a manual to hand for your stat. But if you remove the stats cover you can check the cover it should have a mini guide on it. If not then you have wire somewhere in the wrong place and needs...

What happens with hot water is the boiler ignits and goes to HIGH FLAME the omg i need to shove a shed load of heat to the hw circit and as it gets nice and hot it should reduce to a low flame and control the heat to the hot water by altering the burner pressure. this is normaly done by the...

on your boiler look where the pipes go if they go above it their should be a vent or a pipe that runs up to your tank this should be clear and venting to get the water out. but anywhere above the boiler and pump if u can vent above them do so. If not remove the screw slightly on the pump...

If you got the wiring guide for your stat great whip it out and if you are happy to and have a multi meter handly whack it on the neutral and common and see if you got 240v if so good, now check for calling, if you cant find the wiring guide maybe pass us on the name and make or even a picture...

One thing i advise Get a magno clean in the system this has a nice magnet that collects all the black muck into a plastic box you can take out and clean may help your system fit it on the return and in a few days clean it (you can do this) and you be surprised at the stuff it picks up. I...

Are you getting Central Heating ? The gear your moving is it a valve what type do you have 3 pipes or 2 and the make of the valve. But if you are getting hot water no Central Heating its possibly the motorized valve that you appear to be moving is either gone or the room stat is broken...

turn the hot water control knob on the user control facia down to lowest and operate boiler if it still gets very hot you have problem with the stat or the pcb/gas valve may not be modulating to a low flame (sticking). Try the first method if the hot water runs cold then you know the stat is...

Check the pipes up to the valve when heating is on and the radiator. If the rad bottom half is hot its air vent it useral stuff If the TRV which is in your picture was in the off spot it could of stuck using a light handle of a spanner or something or the head of the TRV bash the spindle...

Please read the commisoning guide for your digi stat at the following link http://www.gasapplianceguide.co.uk/Digistat%20Instructions.pdf

How Recently? First things to do check the pipes. 4 pipes and one that goes out the wall CHF HW GAS CW CHR are normaly the pipe setup check the pipes and make sure in hot water mode CW pipe or mains is cold if its hot its back to front ive seen so many plonkers put them the wrong way...

Very black, is a sign of magnacite in the system basicly the radiatoers rad valves copper tube are all rusting against each other and this is causing strain on your boiler. Its worth considering a Magno clean for your system it has a big magnet that grabs all this metal fragments and stops it...

its probably in your central heating circit their should be a vent on the highest point on your central heating or your pump. Pump as either a screw and turning that slowly a few turns will allow air out, if you have a myson pump you will have a nut like plastic cover screw that around with...

sometimes the 3 lines can mean a pcb the big one at the back to the display pcb has had a communication error. there is a way to check and thats to rehome the connection. Over heat should be a H A code on the display "Temp in H e/X > 100c" as per ideals Engie book if this happens when...

Sounds to me like you are getting a blocked/sludged heat exchanger again. If not done so get a magno clean fitted on the system to protect your boiler this has a nice magnet that collects all the debris in a sealed pot that you can isolate and clean regular. The fan could also be the...

Well the Myson the levers break the bits inside the head break and generaly fail more then i have had on honeywell. Honeywell all that i every realy need to worry about is the motor going. Both valves suffer from sludge build up on the valves seating and stoping them closing and letting by...
