--- title: "Frymaster E42: the vat did not empty during filtration" description: "What E42 means on Frymaster E42: the vat did not empty during filtrations, what to check before booking, and when it is not a failure at all." url: "https://commercialappliancerepair.center/error-codes/frymaster-e42/" --- # Frymaster E42: the vat did not empty during filtration During automatic filtration the FQ4000 opens the drain and expects the oil level to drop. ## What E42 actually means. During automatic filtration the FQ4000 opens the drain and expects the oil level to drop. If it does not, the controller logs E42 and asks the operator to clear the drain and follow the prompts. Breading and crumbs packed into the drain opening are the usual cause. Frymaster commercial appliance display · also shown as CLOGGED DRAIN (Gas) What to do when E42 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). Frymaster lists E42 for gas FilterQuick fryers. ## Before you book, in this order. Each step comes from Frymaster's own guidance for E42 on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Let the controller finish its prompts and keep the vat closed while hot oil is still inside. 02 Once the fryer is off and the oil has cooled, clear the drain opening with the clean-out rod supplied for the fryer, as your staff are trained, never by hand. 03 Skim crumbs more often during service; if E42 repeats with a clean drain, the drain valve itself needs a technician. ### 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 E42 is a flow problem, not a valve position problem: when the valve itself fails to confirm open or closed, the fryer logs E32 or E33. It is also different from E39, which is the filter pad reminder. ## What you may notice with it. The commercial appliance problem E42 tends to arrive with.

Let the controller finish its prompts and keep the vat closed while hot oil is still inside. If it comes back, it needs a visit. ### What clogs the drain on a Frymaster FilterQuick? Crumbs and breading that settle in the bottom of the frypot. Heavy breaded menus need more frequent skimming and filtering. ### Is it safe to poke the Frymaster drain while oil is hot? No. Clearing the drain is done with the fryer off and the oil cooled, using the rod meant for it. Hot oil released suddenly can burn anyone nearby. ### Does E42 stop the Frymaster from cooking? The filter cycle stops until the drain is cleared and the prompts are completed. Whether cooking can continue depends on how much oil is left in the vat. --- **[Read on the site: Frymaster E42: the vat did not empty during filtration](https://commercialappliancerepair.center/error-codes/frymaster-e42/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
