Make sure there are good connections from the amp to the reverb tank (RCA ???), Try to clean up the socket of valves (6V6 and 12ax7), try spare valves; 8)
Take care about high votages, make sure all manipulations are done in safety mode.

If it's still under warranty, you could get fender to take a look at it.

+1 on trying spare tubes.

The tubes would be the first things to suspect. It could be V3 (6V6), or even V1 or V2 (12AX7s), all three tubes are in the reverb circuit. :idea:
