Daily Maintenance
If your machine has an electric heater or heaters in the wash tank, it’s time to clean those now. The heater
coils will be located directly under the low water probe. Using a wire brush or scouring pad clean the exposed
heating coils on the heater or heaters, directing all debris into the drain.
Now that the wash cabinet, filters, wash tank reservoir, low water probe, and electric heater or heaters (if
applicable) have been cleaned. You can now put the filters back in place.
Inspect all the spray jets, look for any that are missing, obstructed, or worn out. If you find any jets missing or
worn out, contact Douglas Machines Corp. for a replacement. If you find any jets obstructed. Try to remove
the obstruction by pulling it out or by forcing it back into the jet pipe. If you need to force it back into the jet
pipe you’ll need to remove the jet pipe end cap (reference your parts manual for jet pipe end cap location) in
order to remove the obstruction from the pipe.
Clean the outside of the machine. Using a stainless steel cleaner or soft cloth with a mild detergent wipe
down the outside of the machine.
Close the drain valve, check that the filters are back in place, and turn the main power back on. Wait to refill
the machine till you’re ready to wash again (it’s easier and less expensive to heat warm water then cold). The
machine is now ready for the next shift or next day of washing.
Periodic Maintenance
Wash pump motor lubrication. You’ll find two- (2) grease fitting on the top of the wash pump motor, one- (1)
at each end. You’ll need to grease these under normal conditions every 90 days. Use an electric motor bearing
grease similar to Shell Dollum or Chevron SRI.
The removal of lime and or scale may be necessary at certain times. This will vary due to the condition of your
water. If you’re finding lime and scale building up on the interior walls of the machine, chances are they’re
also building up in the piping. This could impair washing ability. You’ll need to use some sort of lime and scale
removal chemical. Whatever you decide to use please make sure it’s safe to use on stainless steel, bronze,
and brass. If you have any questions on what to use or how to use it, do not hesitate to contact Douglas
Machines Corp.
Electrical Connections – The first 6 months that you have your unit, you should go over all wire connections in
the electric panels as well as check the wire nuts on all motor leads. After the first 6 months, you should only
need to do this every 90 days.
