Note - Recycler Models Only

If you have low to no suction due to a clog by residue building up over time, there is a feature on vacuum to keep it running until a service technician can troubleshoot the problem. Turn the water by-pass valve to the OPEN position. This will by-pass the recycler and may keep the pump running.
