Any sounds coming from the pump?

The OM drum is probably not indexing correctly.Look on RC,it's a semi-common problem.

thats what i find:
When the drum rotates to two outputs, remember that it is cutting off flow to the other two outputs. The water in the pipes that are no longer getting flow tries to flow backward against the OM4way. That sometimes results in "water hammer" or a "thumping" or "shaking" of the OM4way. This is resolved by drilling small holes (1/8" or 1/4") in the closed side of the drum unit. These small holes allow some of the water to flow backwards just enough to prevent the noise and vibration.
will drill tomorrow
