Hi, I have the same problem, I have just changed the outlet pump $22 as there was water inside of it. Still had problem thinking do I change the inlet valve, $40. A few minutes ago I found the following site which makes sense that it will be a problem on the circuit board

I might just give it a few hits, and if there is no joy, it will go to the tip. His fix was too involved for me and it still failed.
Good luck,
Stephen
