I am running a Boxer 318. I have been dealing with a damper letting water pour into the wast tank for over a year. I have brought in twice and it happens 6 months later. I have puled it apart many times thinking it was getting stuck open from debris but this never helped. This last time i noticed a load clicking. I noticed it was trying to stop the water from going into the wast tank as it was clicking. I bought a completely new damper and solenoid, hooked it up and still the same problem. Any ideas of what to do next?
