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.

What to do when E42 shows on the commercial applianceKind of codeWater, 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.

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.
Let the controller finish its prompts and keep the vat closed while hot oil is still inside.
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.
Skim crumbs more often during service; if E42 repeats with a clean drain, the drain valve itself needs a technician.
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.

A booking with a code goes further when it has the code as shown, the model and serial from the data plate, and a word on whether the unit still holds temperature, heats, rinses or spins. With those three, the office can match the likely part to your unit the same day.
