Remeha error code E5
Posted by jpluimers on 2017/04/28
Some notes as we got an error code 5 (the display showing E5) a while ago.
Our solution was to keep the reset button pressed for a few seconds, then wait for a “reboot” to happen.
Videos from someone else having searched for the E5 cause for 2 months:
- After 5 tries to fire up, it gives error E 5.
- For this particular device, the problem occurs multiple times a day with various intervals between ignitions.
- Rarely it generates error E6 in stead of E5.
- Most often it needs more than one but less than five ignition attempts, so then it does not generate an error.
- The actual cause is a too low ionisation current: the current needs to be between 3 and 9 microAmpere.
E6 was already hinting at a faulty transformer, but the ionisation current definitely confirms that.

Later: we ran into the above problem as well; the problem was the ignition transformer that could not keep the gas ignition current between 3 and 9 µA. The solution was this Remeha part [WayBack] Remeha ontstekingstrafo (incl. ionisatieelectrode) S100012 | Warmteservice. We got there after replacing the burner gasket ring [WayBack] Remeha pakkingring voor brander S103172 | Warmteservice that often solves the problem, is much cheaper and should be replaced every 2 years anyway.

Actually this was the first ever problem that we had with any Remeha central heating system.
