What F2
actually means.
Dexter reports a slow fill with F2 and keeps washing. Owners see it flash on the display; the causes Dexter lists are water valves, incoming pressure, blocked flow and a drain valve that is not closing.

What to do when F2 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 Dexter's own guidance for F2 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Check that the building's water supply to the machine is fully open.
Compare with neighboring machines to rule out a store-wide pressure drop.
Book a visit if only this machine is slow, so valves and inlet screens can be checked.
What not to do
F2 on a Dexter front-load is a fill warning; on a Dexter tumbler, F2 means an open temperature sensor. It does not stop the cycle the way a door lock error does.

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.
