ecomax

So far 2 engineers from different companies have failed to diagnose this problem, one replaced the diverted valve & flushed the system, the other cleaned the burner to correct the flue emissions. I would like to point the next engineer in the right direction. When the problem occurs, the boiler...

Anyone worked on these boilers (My first) The faulty Exp/vessel has caused the O rings on the heat exchanger to pop.I have replaced them all including the exp/vessel, but the left hand 10ma fuse on the PCB keeps blowing (The pcb was bone dry no water had got onto it) I'm sick of buying fuses and...

Last Thursday morning our Valliant Ecomax vU186EH boiler just stopped working with F.21 showing on the display. Pressing the reset switch would NOT reset it- it was dead to the world. Valliant engineer came out this morning- replaced the PCB- boiler fired and stayed on. Yet a few hours later...

hello everyone, having a few issues with this boiler, most have been resolved with the exception of the following. boiler doesnt seem to operate correctly in conjunction with the temp control on front panel, if set to say 70 the boiler reaches 70 fine then keeps going to max...

evenin lads....went to a noisy ecomax pro 18 today...took the cover off and smelled gas and saw scorch marks around the burner....i know that there is a problem with the gaskets on these and the glow worms and the gaskets need replacing with the graphite upgrades...just wondering how difficult...

I have a leak on my Vailant. It appears to be coming from the bottom of the combustion chamber. I didn't want to go poking about inside without some advice. Is it likely to just be a seal on what I assume is just a sensor cable or should there not be water on the other side of there anyway...

My Vaillant Exomax 835 is losing pressure and I have top it up daily to 1.0 - 1.5 bar to use it. Water coming out of the overflow outside (did the bag on pipe test) so i believe it to be the expansion vessel. I turned off the boiler, emptied the water down to 0 bar and depressed the schrader...

Got a job repairing an ecomax showing fault code F32. First time i've had to deal with this. Any tips? Thanks

hello, i've got a new customer that has a problem with a vailliant ecomax combi, she has problem with hot water temp going hot and cold when using the shower, sometimes when turning the hot taps on she gets nothing at all, its on a gas board contract and they have changed diverter valve, and...

Hi, I currently have identified the pressure gauge on my Vaillant Ecomax 835E boiler is faulty. I fully drained the system and all rads and it still showed 1.5 bar pressure. After wiggling and gently tapping the manometer tube and device it slowly returned back to 0.5 bar. Once i closed all rad...

hi, hope someone can help. I'm looking after a property with the above boiler installed. There have been problems with the water temperature and a plumber was called out - apparently needs a new heat exchange valve. Quoted £180+VAT+labour. Does this sound right and would it take long to replace...

boiler is fitted on an open vented y plan system. Fan starts for a few seconds then nothing. Fault code 05 F. Pointing to overheat in instructions however I have reset the boiler. Could be faulty overheat stat or fan I'm thinking. Ringing vaillant technical tomorrow for advice. Until then, any...

Boiler stopped working last Thursday Pressure was virtually non-existant (got a leak in the system somewhere, because it does reuire filling on a "quite regular" basis). So I top it to 2 bar via the filling loop. I tried resetting it at the fused spur. When switched off and on at mains, it...

I am having problems with my boiler. Keeps cutting out and coming up with fault code F23. I have changed the auto air vent. Boiler worked ok for a few days but back to cutting out. We are in process of fitting bathroom suite so water keeps getting turned off could this be causing the probem

Hi, hope someone can help. I have an ecomax 824/2 installed in 2007 , 2 things 1. i have the dhw thermostat set at 53 degrees but when i open the hot tap (bath) the temp on the boiler shows 82 degrees after 5 mins or so, although the water at the tap seems ok 53 degrees is this correct? 2...

I have a F32 fault on my Vaillant Ecomax 824/2E Boiler. The fan is also making a noise, but not sure if that's a red herring. On pressing the reset button the boiler starts and the fan activates, however this appears to keep going and the temperature keeps increasing. The pressure gauge also...

HI We had a vaillant boiler Ecomax 835/e installed in 2005 which has now gone wrong and needs replacing. In order to cut down on costs I want to replace like for like, but can't seem to find this boiler for sale anymore. If I choose another boiler i guess all pipework, flues etc will also...
