i went to a property the other week ,to a gas leak, the leak was found on the hose caused by a rat this was easy to identify as it was behind a free standing cooker.
you could have a blockage in the cold feed from the small tank, follow the pipe then get a magnet and put on the cold feed aprox 3 inch from where it connects to the system , if you feel resistance then thats where the blockage is. when your rads are working again check for cold spots at the...
time to get it serviced it could be the water throttle head dout its the 3 way valve. look up the gas safe web site there you can a qualefied engineer who will fix it and give it a long over due service, easy repair for the pro. remember a boiler needs tlc just like a car from time to time you...
i would pay the xtra 200 quid for the worcester greenstar 30 cdi. havent found many faults on these.good boiler. if money is tight look at the ideal iogic 30. but stay away from the vokera.
no you can buy the head seperately, you can do it your self if your capable
I am gessing that you are a gassafe engineer. so you should understand that with all the years of training we all have & the importance to know your way around a boiler, to ensure it is safe and in good working...
picasso is wrong if the diverter motor is blowing the fuses the cartridge is leaking into the motor so both will need replacing also the flow sensor is natorious on these get a gassafe engineer to check for moisture on the lead. picasso shouldnt be telling un qualefied people to repair there own...
with the heating switched off. turn dhw on ,feal the far left pipe under boiler this is the ch flow, if it heats up then yes it will be div, check you dont have a dripping hot tap somewhere
if the pressure is below 3 bar and the prv is still leaking outside then it will require replacing. i would also have the pressure checked again on the expansion vessel, if it has lost all the pressure again then yes there is a leak and that will need replacing.
Why didnt the 2nd engineer recharge the expansion vessel & change the prv when he come to check your boiler, dont let them say you need replacement without checking it first prob needs pumping up. not for diyers though.
