If you take care of the filtration system, the filtration system will take care of you. The filtration system working properly is essential to maintaining oil quality and maximizing oil life.
The hybrid pressure fryers have a crumb catcher (6) through which the oil passes first when drained during an express clean. This catches all of the big crumbs and reduces the likelihood of clogs in the rest of the filter assembly. This crumb catcher should be emptied after lunch and EOD. The open fryers do not have a crumb catcher.
The filter screen assembly can be used with either a single-use filter (5) or a Masterfil reusable filter. The single-use filter needs replaced daily. Masterfil reusable filters need scraped off daily but only need replaced approximately once a week. We use Masterfil reusable filters. They are more expensive but also more convenient. Either way, the filter envelopes a metal woven screen (3) which further helps with filtering out debris before oil is pumped back into the fry pot.
When cleaning the filter pan assembly, only soap and water is needed, no heavy-duty cleaners or degreasers. Also, it is very important for all of the components to be dried completely before reassembling. Any water present will cause the oil to break down more rapidly and can cause corrosion in the filter pump assembly and cause it to break.
Best practice for putting the filter on the woven screen is to insert the woven screen, fold the open corners of the filter in, fold the open end of the filter down twice, then clip in place. This will minimize the likelihood of crumbs getting through the filter.
The open potato fryer has a thumb latch that needs to be unlatched before the filter pan assembly can be pulled out.
Another difference with the open potato fryer is a small opening in the filter pan's lid, directly beneath the pickup tube connection, that is intended for catching excess oil that drips out when removing the filter pan assembly.
Also, while the hybrid pressure fryer does not have any o-rings that need maintained, the open potato fryer has black o-rings on the filter pan and orange o-rings on the reserve oil pan that need monitored and maintained. Worn out, torn, or missing o-rings will result in open connections and cause the pumps to pull air in, making them operate less effectively and get damaged if left unaddressed.
When replacing the filter pan assembly in the open potato fryer, 1) make sure the thumb latch latches closed, and 2) do not push the pan in with feet or too aggressively. There is a switch at the back of fryer that gets pressed when the filter pan is replaced, and it is responsible for monitoring how frequently the filter pan is getting cleaned. This switch can get damaged if the filter pan is slammed into it too aggressively.

If the fryer is not pumping, first make sure there is power and that the motor reset button—the red button directly on the motor at the back of the fryer—is not tripped.
Warning: Resetting the pump motor repeatedly will burn it out. This is an emergency measure only.
Leaking from the hose's quick-connect nozzle is most likely due to debris blocking the nipple from closing completely, which is caused by poor cleaning of the filtration system.
If the pump motor is running but not pumping oil, first check all of the connections, o-rings, and drain valve. If everything looks okay, the problem is probably in the seal kit—a set of gaskets and nuts located between the pump and the motor.
Slow filtration can be caused by a dirty filter pan, a clog somewhere in the lines, a clog in the pump, or loose gaskets or connections.
Dirty filters can put strain on the pump motor, cause overheating, and burn out the motor.
