--- title: "Frymaster E41: the controller thinks oil is sitting in the filter pan" description: "What E41 means on Frymaster E41: the controller thinks oil is sitting in the filter pans, what to check before booking, and when it is not a failure at all." url: "https://commercialappliancerepair.center/error-codes/frymaster-e41/" --- # Frymaster E41: the controller thinks oil is sitting in the filter pan Before it drains a vat, the FQ4000 wants an empty filter pan. ## What E41 actually means. Before it drains a vat, the FQ4000 wants an empty filter pan. If a previous filtration did not return all the oil, or a drain was opened manually, the controller logs E41 and asks the operator to deal with the pan. Draining another full vat into a pan that already holds oil could overflow it. Frymaster commercial appliance display · also shown as OIL IN PAN ERROR, E22 (M3000) What to do when E41 shows on the commercial appliance ### Kind of code Water, fill and drain Water is not arriving, not reaching its level, not heating or not leaving on time. A dish machine may be short of fill because a supply valve is half closed or its line strainer is clogged, it may drain slowly through a scrap basket full of debris, or its booster may be too scaled to heat the rinse; a combi's steam generator may be scaled or its water treatment exhausted; a washer-extractor may time out on a slow drain. Opening the supply valve, cleaning strainers with the unit off and checking the drain line are fair; a pump, a fill valve, a heater or a leak near wiring is a visit. ### Usually leads to Dish machine repair Undercounter, door-type and conveyor dish machines: tank heaters, boosters, wash pumps, fill and drain valves. ### Shows up as Commercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone. ### Make Frymaster A Frymaster fryer is serviced cold: the visit waits until the oil has come down and the vat has been drained by the crew. ### Source Frymaster FilterQuick FQG30U easyTouch gas fryer manual with FQ4000 controller (error log codes, section 5.6) FQ4000 easyTouch touchscreen controller on FilterQuick fryers (FQG30U and related FilterQuick gas and electric models). The M3000 logs the same event as E22 OIL IN PAN ERROR. ## Before you book, in this order. Each step comes from Frymaster's own guidance for E41 on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Follow the prompts on the controller; it will ask whether the pan is empty or offer to return the oil to the vat. 02 If you check the pan by eye, wait for it to cool and use heat-resistant gloves; never push a full, hot pan back and forth. 03 If the pan is empty and E41 still appears, the pan sensing and the return side of the filter system need a technician; book a visit. ### Still there? It usually turns into [dish machine repair](https://commercialappliancerepair.center/services/dish-machine-repair/). Book with the code and the model number. ### What not to do E41 does not mean the fryer is leaking; it is a guard against overfilling the pan. If oil actually appears under the fryer, treat it as a spill, keep people clear and book a visit. ## What you may notice with it. The commercial appliance problems E41 tends to arrive with.

Follow the prompts on the controller; it will ask whether the pan is empty or offer to return the oil to the vat. If it comes back, it needs a visit. ### Why does my Frymaster say oil is in the pan when it is empty? The controller works from what the last filtration reported, not from a look into the pan. If the pan is truly empty, answering the prompt usually clears it; a repeat means the sensing needs testing. ### Can E41 on a Frymaster lead to a spill? The error exists to prevent one. Draining a full vat on top of oil already in the pan is how pans overflow, so the fryer stops and asks first. ### What happens to auto filtration after E41 on a Frymaster? It waits until the pan question is answered. Several incomplete filtrations in a row lead to SERVICE REQUIRED and disabled filtering. --- **[Read on the site: Frymaster E41: the controller thinks oil is sitting in the filter pan](https://commercialappliancerepair.center/error-codes/frymaster-e41/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
