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.
Hi All,
Problem with a GW 18HXi reporting error F13 (PCB Fault). I've replaced all the electrolytic capacitors on the PCB, many bulging with high ESR. After reassembly the fault remains. Swapped board with a known good one and the fault remains.
Any ideas?
Hi
Can anyone help?
I've got a problem with an intermittent EA fault on a Worcester Greenstar 38CDi Classic GC 47-406-38. I was called out to it but couldn't get it to go to fault- each time it fired up however, on a video the customer took he kept having to reset it.
I checked the gas rate...
Hey Guys
just wondering if anyone on here has had this problem with a toilet pan before, this is the 3rd toilet pan I’ve had this problem with in the past 18 months lol, also each pan is a different make from a completely different supplier hence why it’s so bizarre, I think it’s just bad Luck...

Replaced a main heat ex today for a customer on an ideal isar, heating is ok but when running hot water it overheats and comes up with HA fault code, only happens on hot water though. Any way to shift the air from the plate heat ex? Its situated flat in these boilers instead of the usual on its...
Pressure is ok but increased to see if boiler would click into action but didn’t, have reduced back, needle is moving on pressure gauge, have tried reset but still nothing, any ideas before I call someone out? Thanks
Hi
I have a Telford tempest unvented cylinder and I'm finding that when the hot water is on and I turn it off on the programmer the TPRV opens and let's the hot water out. Only stops running when it cools down again.
What I find strange is that it only happens if I turn the programmer off. If...
Hello All
I have a Bristan mixer shower. Pressure is excellent and I have replaced all seals on the Thermostatic cartridge. The CD valve is turning easily and 'looks' as if it is ok.
Unfortunately the temperature dial does not make any meaningful difference in the temperature which is tepid...
Hi.
I've been out to look at this boiler today (I am a gas engineer) and found that this FF fault code keeps coming up even after restarting the boiler.
On arrival I found pressure was on zero so I topped it back up and reset the boiler.
On the display it says 141 then changes to...
Morning all,
We inherited a c.2007 Heatline Compact boiler when we moved into our house.
On Friday the boiler developed an air pressure fault. I first tested the air pressure switch in both the Common-normally closed and Common-normally open positions and both are working ok. I even tried a...
Basically the boiler stops working intermittenty for heatingand water... It had a leak from auto air vent which was dripping into the APS which has been repaired..
Everything seems to be working I've tested the harness to the APS and the overheat stat. and out of desperation changed the PCB...
Hello
Our Vaillant boiler has developed a fault in the last 2 weeks. The hot water is working without any problems. However, within 15-20 minutes of turning the heating on we are getting the error message 'F.75 Fault. Pump water shortage'. The boiler being on for heating is pushing the filling...

Evening all,
I am the unfortunate owner of a very large gravity fed floor standing gas boiler. A few days ago the boiler decided not to come on when there was demand. The pilot light remained on. After a quick look over and attempted relighting the pilot light went out and would never stay...
Hi I have an Ideal Logic+heat 24 (Not Combi) it is: Alternatly flashing between: 0 (on its own) and C (on its own) when in central heating mode, it works fine on water only, any idea as to the fault?
many thanks
Tom
Over the last couple of weeks my boiler has started to throw the occasional S.54 and F.64 codes. I know when its happened because the hot taps run cold.
The whole system is 8 years old and has been serviced every other year.
Normal service is resumed by pressing the reset button.
The question is...
I have a problem with my Viessmann Vitodens 100 WB1B-26 boiler. It has had this problem since it was installed (Dec 2012), but is worse this year due to the very warm winter in my area (Philadelphia, PA USA). The problem goes like this. From midnight to 10 AM, the boiler works fine. But when...
Hi guys, commissioned a Intergas ssyem boiler today. Work fine until later on it went to lock out code11?
I know the combi Intergas boilers require to set the parameters for a combi but does this boiler need to beset for a system boiler?
Nothing states in the manual about setting the...
Can anyone recommend? .... training in heatpumps, books or web links on fault finding said heat pumps and a good place to get some experience- I'm looking to expand my knowledge.
I've done a taster course a few years back at colledge but that info has rusted in the back of my brain.
Hi, after some advice.... We have a faulty 3 way diverter valve on on our hot water tank. So we have to put heating and hot water on at same time to have both working. No an issue as its winter..
However, our automatic timer doesn't work on the honey well control panel to allow us to preset...
