Possible, would be something blocking the impellors, You would need to disconnect the pump to have a look. 1st though check the spray arms are clear etc. Use drain pipe to get as much water as possible out, push it as flat to floor as you can, but keeping the very end up, use a low level bowl or something to catch water. I then usually put several dust sheets/old towels on floor, turn m/c onto its side, on the towels, catch any more water, then very easy to unclip the pipes to the main pump, check all pipes are clear, If clear, could be pump is faulty, running slow. Have had the wire from controller to pump motor break on one of them. But if you can hear the pump, it is running, unless intermittent, Make sure that you have disconnected from mains, use test meter to check wires from motor to controller, the front dials pull off, screws down sides, front panel will lift off.
