I have a Bailey Ranger (2001) fitted with a 10L Truma Ultrastore gas/ 450Wmains water heater (US103-11201186) which I only run on electricity. The van was serviced before our first trip of the season and all was apparently working.
We had hot water for 3 days but then the campsite hookup tripped and after a process of elimination I diagnose a problem with the water heater!
Ironically the van's power circuit breakers did not trip and the fuse to the element did not blow either. However 450W should only draw about 2A but was fitted with a 5A fuse.
On returning home I checked the element, which has a resistance of about 116 ohms. In the even that the tripping of the campsite bollard was a coincidence I tried it again. The relevant circuit breaker tripped in the house but not in the van nor blew the fuse! I was unable to measure any resistance between live and earth below 2M ohms (max on my multimeter) although I do suspect some leakage to earth.
If this were a domestic immersion heater I would just replace it in a flash as it could be done for about £15 but one for the Truma costs £55-£60!
I suspect that I will have to bite the bullet but just wondered if I had 'missed' something obvious before paying the money.
Please can anyone advise?

i've just gone through the exact same sequence of events , but with 240v element on my dometic dual fuel fridge , each time blowing the trip on the hook-up post rather than anything in the van , the element even passed the resistance test .The replacement element for this , was a lot cheaper (£24 from ebay) , but solved the problem instantly ! , have a look on ebay for your element as the RRP for mine was £40 inc vat .
Hope this helps.

UPDATE
Thank you all for you helpful advice and suggestions.
I bit the bullet and ordered a replacement element via eBay for the best price I could find of £53.98 inc P&P.
I was a little concerned about actually changing the part as it is 'hidden' behind a cardboard cover. In fact there is a 'starburst' cutout (I can't think of any otherway of describing it) which give sufficient access to replace the element. It was much simpler than I expected (unusual) and we now have hot water again, much to my other half's relief.
