Is my water heater safe to use?

I have a Truma Ultrastore combined electric and gas water heater.  I drained it down prior to returning home on Friday, but for family reasons had to divert to another site for an extra night.  Being a numpty I forgot that the water heater tank would need
to fill up again (we have an onboard cold water tank which I had refilled), so a short while after I switched the heater on, the fuses tripped. Recognising my mistake I ran the hot tap until water came through, thus filling the hot tank.  The heater worked
for a while then tripped again, and now trips every time I switch on.  I suspect I need a new element.

 The water heater is under the seat, but positioned so that the element is against a wall, so the whole unit will have to come out, quite a major job.  I am away again at the end of the week so want to put this
off.  My question: Is it safe to use the gas water heater for the time being?
