Water Heater Autosleeper Fairford

Recently on holiday in France and first site water not heating up. Code W 45 H on panel, which suggests I should 'reset overheating protection' or replace fuse. 
I removed the metal shield over the heater at back of van, and then manual simply suggests 'remove connection cover and press red reset button'.
I could not get hand between side of van and heater to do this. Also, didn't want to force anything. Is this meant to be an easy thing to do? Any advice?
Thank you!

I had it a few times when I used to go on EHU, can’t remember how but it was any easy fix, turning everything off and back on rings a bell.
This may help.

We tried this but didn't seem to change anything.
Thank you anyway.

This type of fault happens when you don't close down the heater properly  before you unplug electric. Hold the close button down for at least ten seconds, if you don't it only goes into standby and does not close down completely.

On numerous occasions that was exactly my mistake Paul, I used to unplug the EHU without a thought about the Truma.
That was the reason I suggested powering everything down in my earlier post.

Thank you Paul - when you say 'close button', do you mean turning OFF on the panel.
Will bear that in mind in future!

Yes , hold it for the ten seconds.

Here's a previous thread on that fault code....
