fault
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep.A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault.A fault zone is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the distinction, as the rock between the faults is converted to fault-bound lenses of rock and then progressively crushed.
My own boiler at home has developed an intermittent fault causing an ignition lock out every week or two when there is a demand for hot water. When reset the boiler runs without issue for a week or two. This fault only occurs on HW demand, there has never been a lock out on CH demand. Ideal tech...
Renewed room thermostat and 3 port valve(drayton MA1) but hot water fires up OK but not central heating unless I turn off hot water timer settings on drayton lp522 controller?
I am a new poster to this forum - not a heating professional, but a householder looking for advice. please.
I have a Glow worm 18hxi boiler with Magnatech installed in 2006 by a local engineer who has serviced it regularly and comprehensively every year - very competent, has done a lot of work...

Hi there
I was called out tonight, no heating no h/w.
Pump would run, pump proving made (continuity across connections at board), no power to fan across L-N, but getting 240v L-E. Going back tomorrow with the PCB but just wanted to confirm this diagnosis. The fan resistance was 30.6 ohms which...
Hello,
I have a boiler engineer coming out, but it's not till next week, so I was just curious if anyone knew what this fault could be in case it was something obvious, it's the first I've tried heating since May...

No error messages, hot water is fine, but no heat. Even...
Noticed that when we turn the heating on manually we would then notice it had gone back off again so set to continuous and saw this
video has sound
Does this look like a faulty timer or something else tripping it?
Thanks
Hi guys, it's my boiler I've had an issue with. I've turned the boiler off and drained my system tonight to remove a couple a rads, and as my hot water has beem getting cooler I've gave the plate a clean out too, got filled back up and turned boiler on and was given the 3l fault code which...
Anyone had any experience with F54 & F28 fault code on a Vaillant Eco tec plus 831?
It locks out but if you leave it for a while, sometimes days, it fires back up. Fiddled about with the wiring harness and it seemed to sort it for a while, but not sure if that was coincidents. I'm guessing it...
Got a Glow worm 18 flexicom with f22 fault.
I've replaced both flow & return thermistors, bleed all rads of air, removed the pump and cleaned it, it all seems fine and pump is strong, checked wiring continuity and that's all good. Boiler is only 6 years old and Glow worm have said it sounds like...
Hi all, I'm going to be getting my cookers ticket soon and I'm a little confused on the classification for faults. If I turn a gas oven on and its starts on high flame what would this be classed as?
Also for things such as fsds on hob burners I am assuming that if it doesnt keep the burner lit...
Hi I have an issue, couple of day ago no water. Boiler worked ol for heating so looked at syncho motor ( had to replace this about 5 years ago on the same system). Motor was working but when I checked it it was not opening the water valve enough to actually make the contact switch to tell the...
Hi, is there any ferroli experts here? Looking for some advice on a Ferroli i29, attended a couple of times on an A01 fault code, cleaned condensate trap, hose, also connection at p trap. Tested all working when left on both occasions but the fault reoccurs in a week. Any advice would be greatly...
Hi
I have a permanent A21 fault on my Greenstar Comfort RF receiver on my boiler. I am unable to access the settings as it does not respond to any input from the buttons on the panel. My thermostat is showing an A28 fault. My thermostat was not working so I disconnected it from the receiver in...
Hi, new to the forum and looking for some advice if possible. I had an engineer out to look at my combi boiler (potterton performa). The power light is coming on, but no response to demand for hot water or central heating.
The engineer had a look inside and found the PCB was getting 240V in...
hi guys, pressure had zeroed so topped up pressure. Boiler still flashes ea code, when you reset the boiler you can hear the electrodes trying to spark.
I'm going back tomorrow my plan is to do a gas pressure test on the inlet. If there's no pressure ill remove gas valve and see if there's any...
Hi guys! I'm looking for help from a Plumber with 5+ years of experience for my NVQ L2 evidence work,which will enable me to attend onsite assessment. I think it should not take more then 1 day to complete it.I just need to make some pictures that i am solving a problem basically and write down...
