It's only 2 1/2 years old, however it's made by montpellier and it's a pain to get bits for, the photo looks as If it's all rusted but it isn't, it's just residue from washing powder.

My washing machine was banging so I assumed it was the bearing, I spent 2 hours getting into the guts of it so now it's just an empty metal box and bits, I think I remember where everything goes, it wasnt the bearings, the "spider " at the back cracked, the picture looks like it's really...

OK, here's the full problem, the boiler keeps short cycling, the flame stays on but dies down, initially I thought as this was affecting the water temp, hot /lukewarm it was related to the water or heat exchanger, however the boiler locks out without water on, seems water just goes cold...

The pump seems to be moving the water, however Pump is getting very hot indeed, I've removed the small metal disk and it does spin freely and doesn't make a noise, please look at attached advice, is this suggesting that I turn boiler back on with the metal disc removed? Won't that throw...

Apologies for ignorance but if I open the filling loop and open a drain tap with hose attached into the drain, won't it just flush through the water until clear, I've see a youtube video where a professional removed a radiator and attached a drain to one side of the fitting and hose providing...

Then I will refill and add cleaner and then flush again and refill

Literally draining system and re filling.

I own a terraced house, the boiler is upstairs, the one Rad with a drain fitting is a step up from the others downstairs so im a bit concerned that the 3 others downstairs won't empty. Can I turn off gas to boiler, leave the cold water flow to the boiler on and attach a hose to the Rad drain...

I have an issue with my ferroli 901 short cycling , it fires up for approx 3 minutes , then shuts down , radiators seem fine, however water runs hot/warm , im assuming this is due to short cycling. i have changed the thermos on the copper pipes and the direct flow meter , ive been told its...

Yeah, I've done those, thanks, So as it stands if it's not the heat exchanger, the symptoms are, Pump is very hot which can't be right Water is hot then warm, Heating seems OK However system does seem to loose pressure when heating not on to the point where pressure is at zero, no...

Thanks , can i just clarify something please? , ive replaced the 2 sensors on the vertical copper pipes that have wires connected to the pcb (no difference) , replaced them both , however I have since seen that there are 2 temperature sensors on the actual heat exchanger , are they the ones you...

Recently I have been getting full CH however hot water runs for a while , then goes warm then fires up again then gets hot for a few minutes and then does the same , ferroli boiler optima 901 , its been suggested that its the heat exchanger , however this morning Ive noticed that the boiler...

Thank you all , I appreciate the advice , you may think that I am ignoring some of you but I am taking it all into consideration . Following on from some advice I swopped the wires so that the hot water sensor wires were on the CH thermo and the CH sensors were on the DHW thermo I discovered...

Ongoing issues with boiler , I require a few answers to a few questions please , it would be great help , going through a process of elimination. Heating seems ok , however water gets hot , runs hot for a few minutes then goes cold , then starts to get hot again . I've changed the thermo on...

ive just had a thought , do both of the thermostats , ch and dhw kick in at same temperature?

Chris , Apologies for this , this is a question in relation to something that you posted over 10 years ago re an optima ferroli boiler giving hot/cold water on and off, , did you ever get to the bottom of this ?, ive got the same problem , any help would be appreciated , Thanks,

Just had another look whilst tap running , flame is constantly on when boiler on , however orange light ignites and flame kicks in when tap on , also fan can be heard , pressure is correct , however after approx 40 seconds flame dies down , and fan stops but then kicks in again and does the same .

Apologies , I meant that I'd replaced the temp sensor on the DHW pipe with no change .

Evening , I appreciate that there are a number of similar issues on this forum and others , however none of these have helped so I'm asking for my specific issue. My boiler is 20 years old , only previous issues have been with PCB which Ive replaced a number of years back My CH is fine ...

My wife has purchased a lightweight ceiling rose (polystyrene) , she's the designer and I'm the magician that's going to make it all happen ( sigh!) It's move or less flat , I've done one before with no issues. I removed the light fitting and there's a lot of wires up there as well as a hook...
