The number one cause of damage to a sealing head is loss of water flow, coupled with a faulty flow switch needing replacement. Here are some simple checks that can save you money and down time.
Check the filter screen in the water pump. Under the large acorn nut on the water pump is a filter screen designed to trap dirt. At least once a month this should be removed, blown-out with an air hose and placed back in the pump.This ensures clean water flow to cool the sealing head.
Check the condition of the flow switch. The flow switch is the most critical part of the water system. It is an open switch that closes when water flow is introduced. This completes the interlock in the start circuit of the capsealer. If there is no water flow it will not start. If the water in the recirculator is dirty, the flow switch builds-up dirt and eventually stays in the closed position. Now, if there no water flow it will allow the capsealer to start because the flow switch is stuck in the closed position. Check your flow switch with an Ohm-meter. If the flow switch is good you will read an open with no water flow and a short when the recirculator is turned on.
Clean the water recirculator. Once or twice a year empty, clean and replace the distilled water and Pillar Defense solution inside of the recirculator.
