occur if the Pump Motor is turned on with no water in the reservoir. The water level marker (
FULL ) is on the inside back wall located under the basket..

close Parts Washer lid, turn pump on for 2 seconds, replace caps hand tight.
3. Make sure the cord is unplugged before draining reservoir.

bottom of reservoir.
6. Take care in cleaning around the heating element and low water float switch.
7. Clean the float switch thoroughly wiping it of all grease and metal filings.
8. Fill with chemistry, allow heat up time.
FOAMING
1. Foaming can be caused by many different reasons such as, cold bath temperature, lack
of cleaning compound from use, extreme amounts of certain greases or gear oil, too long of a
service interval, over contaminated bath, and over time the salts from water that is added to the
bath.

can lodge in the spray jets and restrict the spray.
Remove the pipe caps. With a pick or a drill bit
(no drill motor) push any debris back into the
manifold . Close the Sink/Lid . Turn the cycle timer
on for only 2 second or less, this is enough time
for the pump to send several gallons of cleaning
solution thru the manifold system and flush out all
debris . This process may be performed at any time
necessary.
DO NOT CLEAN MOPS OR RAGS IN THE MODEL 2725.
CLEANING OUT PUMP INTAKE FILTER
Cleaning the pump intake filter each time the
reservoir is drained will keep the Model 2725
performing it’s best . After removing the filter tube
from it’s support bolt, rinse off debris as much as
possible. A wire brush may be used to assist in
removing fibers and build up around the filter holes.
Use an air blow off gun to make sure all filter holes
are clean. Give the filter a final rinse, then reinstall
the filter tube.
