We have a Benimar Tessoro 486 with a dropdown bed. Nearly every trip we've been on the fuse blows and we have to replace it. It is quite a pain because at first it blew while the bed was in the low position, consequently we had to manually crank it up far enough until we could access the fuse box which is tucked away rather awkwardly next to the combi boiler - (it would help if my husband has child sized hands) any way once we can access it we replace fuse (20 amp) as per instructions, and all ok. Anyone else got similar problems ? I wonder what causes this, I would have mentioned this when habitation check is done, but it was cancelled this year because of Covid.
