Hi all hymer 544 when i use the water tap it blows the 5 amp fuse could it be the micro switch thanks Bernie

unlikely to be switch pump or short on wiring would be most likely, try pulling wire off pump to eliminate faulty pump that would be a good start:thumb:

as Mick said...its a process of elimination.

if the fuse blows immediately it could be a trapped/shorted wire....dead short.

if it last a second or two then blows, then it could be the pump has seized....overload

Are you sure 5A is the correct rated fuse. Mine has 10A fuse and can draw 4A+ on startup.
