blown fuse

Help!!
I have a vailant turbo max pro and the fuse in side the front drop down pannel keeps blowing. Is there an obvious problem or will it require the use of a multi tester and service engineer to find the cause? I guess the answer will be " it could be a number of things" but just wondered if there was a specific cause to the problem.
Thank's in advance.
Brian.🙁
