Tunze Recirculation Pump 1073.050 Issue

Hello,

I have a Tunze Recirculation Pump Silence Electronic 1073.050 that I purchased about a year and a half ago. I recently upgraded tanks and I think in the process of setting up the new tank some water may have damaged some of the electronics. In particular, I believe water may have got in the small black control speed box. My pump is now 'revving up' and down randomly, and I can't seem to replicate when it does it, but it happens often (about a dozen times a minute). Because of this, its causing a major issue with draining because I have to constantly adjust my gate valve to the point that I can't use the pump.

Has anyone else experienced this issue before, and is there any remedy or replacement part I can try before having to purchase an entire new pump (which I'd prefer not to).

Thanks in advance for your help!
 
If the end connector is water damaged, if you send it in, it is likely I can repair it. A new end connector is $25 installed.
