We have a Ideal boiler it is displaying a LE fault replaced the PCB and STILL showing same fault! When you rest it is flashes D like its working and goes back to a fault.
Can anyone help?

Ideal Boiler LE fault NOT PCB

Who replaced the pcb? Was it replaced with a brand new one from a parts suppliers? Was the position of the jumpers checked or did they just copy the position on the old pcb?
It was by a registered engineer it is a new part and he replaced it in the same place as the old one. He has now said it MUST be something to do with wires but cant get the part for a week with no hot water and two little ones im hoping theres another solution!
Has he charged you anything as of yet? Le norm means pcb fault, but I'd check the jumpers are fitted in the correct position and not just copied from the old pcb

How do I check the jumpers are in the right place?
Where should they be?
Thank you

This boiler, more that most, does need some product specific knowledge when repairing.
Thats apart from carefully diagnosing rather than just changing parts.
You should NOT be having to pay for his mis-diagnosis if thats the case.
We wonder if he has correctly set the boiler specific settings. They are not always to be in the same position on the old and the new pCBs!
What colours were the old and the new PCBs?

LE? LF is the most common and covers at least 10 different faults on these tubs of lard ! none that i know relate to a PCB issue!
Quite right Kevin, although I do think the PCB is also one of the possibilities.
Even if its not listed, as the PCB which generates the codes thats always possible.
Now the owner does not know if its a different fault or just the RGI has not set the new one correctly.
We are still waiting for the colours!

overheat stat causes LE also
Just the colour of the PCB?
Orange
I agree with engineerman LE is also caused by overheat stat, replace that and should be ok.
It sits above the thermistor on the left hand side.

Lf is prob the most common fault I get on these but the op is saying he is gettin le, which is norm the pcb in my experience
If it's not the PCB I'd say it was overheat.
Check the thermistor is clipped to the pipe properly and that it's not corroded/damaged etc... If the PCB sees the overheat stat is reading 90C but the thermistor is reading below 70C it assumes there's a software fault thus giving LE.
I had this just a couple of weeks ago. The heat ex had leaked condensate water onto the thermistor which meant it didn't go out of range but it did give an inaccurate reading, tricking the PCB into thinking that itself was faulty!
This is the offending Isar piece of s**t
I've never seen LE be anything other than a PCB or, rarely, this.
What else can LE be?
