Single EZ-Topper™ | Pouched Topping Warmer

To take care of this mess maker, check the seals and o-rings. If they look worn with tiny cracks or are misshapen, it's a good time for replacement.

This type of symptom was typically seen in Brazed Style (valve bodies) pumps manufactured prior to 1993. Well done on your pump maintenance, if yours is of that age. Our advice is to make sure the ball is resting on the inner valve assembly inside the cage. If that is correctly placed, also ensure the inner valve handle is on the catch.

The next time your pump is apart for cleaning, check all seals and o-rings for wear or damage. Over time they develop tiny cracks and need to be replaced. Further investigation depends on what style (age) your pump is…

For a Cast Valve with Captured Balls (1999 to present)
Make sure the balls move freely when cleaning.

A Cast Valve with Loose Balls (1993 - 1999)
Make sure the balls are in the proper place; one in the inlet port of the valve body and the other in the discharge port.

For Brazed Valve Bodies (prior to 1993)
Make sure a ball is installed beneath the ball-retaining pin, the retaining pin is in place and a ball is resting on the inner valve assembly under the cage.

First make sure that the seal is firmly installed on the piston and stem assembly, with the flare side of the seal facing down. If the seal was installed properly, it likely needs replacing.

Known to insiders as a plunger problem, it's typically either a missing washer or a broken/missing spring.

The washer is necessary to compress the spring, so if it's missing, your plunger will not return. A well-used spring can become worn out or broken. The spring is also necessary for pump operation. Now you can call yourself an insider too.

Your pump Model and Part number are stamped on the lid. With that information, a parts breakdown will determine replacement part numbers.

Quickly double-check, is the outlet getting power? Do you have too many things plugged into the same outlet or circuit?
Check operation in another outlet.

Did the unit accidentally get wet or submerged?
Save yourself the freight fees and let it fully dry out before sending it in for repair. We have had units returned for repair and with a few days of dry time/transit they started working again.

Has any food waste come in contact with the thermostat?
This can cause the unit to stop heating.

Do you use the unit as a water-bath?
Using treated or softened water and air drying during non-use is a great way to extend the life of the water vessel; prevents water from leaking through a corroded pin-hole onto the electrics within.

Is descaling part of your scheduled maintenance?
Over time, lime scale can build up on the unit and cause it to stop working.
