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. Dexter commercial appliance display · also shown as SLOW FILL ERROR What to do when F2 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 Dexter A Dexter call in a laundromat is often set for opening time, before customers load the row and every pocket of the room is in use. ### Source Dexter common troubleshooting and error code reference for T-Series vended front-loads (Part 8533, 9/19) Dexter T-Series vended front-load machines (T-300 through T-1450) covered by Dexter's 2019 troubleshooting reference; the drive codes come from the variable frequency drive these models use. ## Before you book, in this order. Each step comes from Dexter's own guidance for F2 on its commercial appliances.

Check that the building's water supply to the machine is fully open. If it comes back, it needs a visit. ### Why does my Dexter keep washing with F2 showing? Dexter designed F2 as a warning. The cycle continues, but wash quality suffers with too little water. ### Can a drain valve cause F2 on a Dexter? Yes. If it does not close, water runs out as fast as it comes in. ### Does F2 clear on its own on a Dexter? It clears when the cycle ends, but it will return if the cause stays. --- **[Read on the site: Dexter F2: slow fill, the low level took over 7 minutes](https://commercialappliancerepair.center/error-codes/dexter-f2/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
