About the Meiko USA FV250.2
The Meiko USA FV250.2 is a high-temp pot, pan and utensil washer certified under the ENERGY STAR program for commercial dishwashers. It is rated to process up to 13 racks per hour.
It sanitizes with a final rinse of very hot water — 180 °F (82 °C) at the rinse manifold on most machines — normally produced by a booster heater that raises the building's 140 °F hot water. No chemical sanitizer is needed and ware dries quickly, but the machine depends on a properly sized booster and, depending on its size and local code, a ventilation hood to capture vapor.
According to its certification data, the machine draws 0.84 kW while idling, plus 0.17 kW for the booster heater. The wash area measures 9.09 sq. ft., which determines how many sheet pans and stock pots fit per cycle.

Safety information
- Have the machine installed by a licensed electrician and plumber. Commercial dishwashers are hard-wired, often to 208–240 V or three-phase circuits; switch off and lock out the disconnect before cleaning inside panels or servicing.
- Detergents are highly alkaline and delimers are acidic. Wear chemical-resistant gloves and eye protection, keep Safety Data Sheets on site, and never pour chemicals into the machine by hand unless the manufacturer's procedure calls for it.
- Never mix chlorine-based sanitizer with acid delimers or other chemicals — the reaction releases toxic chlorine gas. Drain and rinse the machine completely between deliming and normal operation.
- Keep the floor around the machine dry and use anti-slip matting; water, food soil and chemical drips make the dish area a common slip hazard.
- Final-rinse water and the steam released when a door or hood opens are hot enough to scald. Let the cycle finish and stand clear of the vapor when opening the machine.
- Keep fingers clear of the door or hood as it closes, and lower it with the handle rather than letting it drop.
Installation and first-time setup
Installation must meet the manufacturer's instructions and local electrical, plumbing, mechanical and health codes. Dimensions and utility requirements are not part of the certification data, so work from the specification sheet for this exact model.
- Plan the utilities
Confirm electrical service (voltage, phase and amperage on the nameplate), a hot water supply of at least 140 °F (60 °C) for the booster heater, a drain sized for the machine's discharge rate, and any required ventilation before the unit is set.
- Position and level the machine
Set the machine level on its legs or stand, with tables or counters arranged so soiled ware moves in one direction and clean ware out the other without crossing back.
- Connect water and treat hard water
Install a shut-off valve, a pressure regulator if supply pressure exceeds the data plate range (final-rinse flow pressure is commonly specified at 15–25 psi), and backflow protection as required by plumbing code. Hard water causes scale on heaters and nozzles and spotty ware; install a softener or scale-control treatment if the manufacturer or your water report calls for it.
- Connect the drain
Connect the drain per local plumbing code — many jurisdictions require an indirect connection with an air gap to a floor sink. Some codes limit drain water temperature; check whether a drain-water tempering kit is needed.
- Booster heater and ventilation
If the booster heater is a separate or optional unit, install it close to the machine with insulated piping; size its electrical circuit to the nameplate. High-temp machines release significant heat and vapor, so install a hood or condensate hood where local mechanical code requires one.
- Set up chemical dispensing
Have your chemical supplier install and calibrate the detergent and rinse-aid pumps. Label every container and route the pickup tubes so they cannot be swapped.
- Commission and verify
Fill and heat the machine, then run test racks. Verify wash and final-rinse temperatures against the data plate with a calibrated thermometer and confirm that ware surfaces reach 160 °F (71 °C) using a maximum-registering thermometer or heat-sensitive label.
Using your dishwasher
Daily start-up
- Check that scrap screens, strainers and wash and rinse arms are in place and that the drain is closed.
- Fill the machine and let it reach operating temperature before washing the first rack.
- Verify chemical containers are not empty and that pickup tubes are submerged in the right products.
- Record the wash and final-rinse temperatures on your log at start-up and periodically through each shift.
Temperature and sanitizer requirements
| Machine category | Minimum wash temperature | Final rinse / sanitizing |
|---|---|---|
| Stationary rack, single temperature | 165 °F (74 °C) | 165 °F (74 °C) |
| Stationary rack, dual temperature | 150 °F (66 °C) | 180 °F (82 °C) |
For hot-water sanitizing, the final rinse must not exceed 194 °F (90 °C) at the manifold, and ware surfaces should reach at least 160 °F (71 °C). Check this weekly with a maximum-registering thermometer or temperature label run through the machine on a plate.
Loading for clean results
- Scrape and pre-soak pans with baked-on or burnt soil; heavy soil exhausts detergent quickly and clogs screens.
- Load sheet pans and hotel pans upright in the pan rack, and position pots and bowls open-side down so they drain and the spray reaches the inside.
- Wash utensils in a single layer in a utensil basket so spray can reach every surface.
- Change the wash water whenever it becomes visibly dirty or greasy, and at least as often as the manufacturer recommends.
- Do not try to exceed the rated 13 racks per hour; cutting cycles short reduces wash and rinse contact time.
Saving energy and water
- Run full racks whenever possible; a half-empty rack uses nearly the same water and energy as a full one.
- Turn the machine off and drain the tank at the end of service rather than leaving it hot overnight.
- Fix leaking rinse valves and worn door gaskets promptly — both waste heated water.
Care and maintenance
| When | What to do |
|---|---|
| After each meal period | Drain the tank, remove and empty scrap screens and baskets, and rinse the interior. Check that wash and rinse arm nozzles are clear. |
| End of each day | Pull and flush the wash and rinse arms, wipe the interior and door or hood gaskets, and leave the door open so the machine can air-dry. |
| Daily | Review the temperature log, check chemical levels, and look for leaks around the pump, drain and doors. |
| Weekly (or as water hardness requires) | Inspect heating elements, the tank and nozzles for white scale and delime with the manufacturer-approved product when scale appears. Rinse thoroughly afterward — never let delimer contact chlorine sanitizer. |
| Monthly | Inspect door gaskets, curtains, hoses and the chemical pump tubing; confirm the thermometers read correctly against a calibrated probe. |
| Every 3–6 months | Schedule preventive service: temperature controls, booster heater, fill valves, pump seals and safety interlocks. |
Troubleshooting
Most dish-machine problems come from temperature, chemistry, water quality or loading. Check these first, and consult the diagnostic code table in your manufacturer's manual if the control displays a code.
| Problem | Possible cause | What to try |
|---|---|---|
| Ware comes out dirty | Wash temperature low; detergent not dispensing; clogged nozzles or full scrap screens; racks overloaded or poorly scraped. | Check temperatures against the data plate; check detergent supply and pump; clean arms and screens; improve scraping and racking. |
| Spots or film on glasses | Hard water or scale; rinse aid empty or set incorrectly; detergent concentration too high. | Delime the machine; refill and adjust rinse aid; have the chemical supplier recalibrate the dispensers; consider water treatment. |
| Machine will not fill or fills slowly | Supply valve closed; clogged inlet strainer; low water pressure; faulty fill solenoid or float. | Open the valve; clean the strainer; check pressure against the data plate; call service if the solenoid or float has failed. |
| Water leaking onto the floor | Door or hood gasket worn or misaligned; curtains missing; drain blocked; table joints not sealed. | Replace or reseat gaskets and curtains; clear the drain; reseal table connections. |
| Excessive foaming | Hand dishwashing soap or wrong detergent in the machine; heavy protein or egg soil; overdosed rinse aid. | Drain and refill; use only machine detergent; pre-scrape more thoroughly; have dispensers checked. |
| Final rinse below 180 °F | Booster heater off or undersized; incoming water below 140 °F; scaled booster element; rinse pressure out of range. | Check the booster breaker and thermostat; raise the building water temperature; delime; adjust the pressure regulator. Do not use the machine until the rinse temperature is corrected. |
| Ware not drying | Final rinse not reaching temperature; rinse aid empty; ware stacked while wet. | Check rinse temperature and rinse aid; let ware air-dry fully in racks before stacking — never towel-dry. |
Energy use and running costs
The table below estimates yearly operating costs for the Meiko USA FV250.2 from its certified ratings, assuming 60 racks per day, 10 hours a day spent hot but idle, 365 days a year, electricity at $0.17/kWh, water and sewer at $0.015/gal, and gas at $1.50/therm for an 80%-efficient building water heater.
| Cost item | Per day | Per year |
|---|---|---|
| Idle energy (1.01 kW for 10 h/day) | 10.1 kWh | $627 |
| Washing energy (0.86 kWh/rack × 60 racks) | 51.6 kWh | $3,202 |
| Estimated total | $3,828 |
Water use for this model is not listed in the certification data in a form that can be converted to a daily figure, so water and water-heating costs are not included in the estimate above.
Every gallon a dish machine uses has to be heated, so lower water use cuts both the water bill and the energy bill. Actual costs depend on your rack count, operating hours, incoming water temperature and utility rates.
Frequently asked questions
Is the Meiko USA FV250.2 a high-temp or low-temp dishwasher?
It is a high-temperature machine that sanitizes with a hot-water final rinse (180 °F at the manifold on most machines), so it needs a booster heater and 140 °F incoming water.
How many racks per hour can the Meiko USA FV250.2 wash?
The certification data lists a capacity of 13 racks per hour. Practical throughput is usually lower because of loading time and soil levels.
How much energy does the Meiko USA FV250.2 use when idle?
Its idle energy rate is 0.84 kW, plus 0.17 kW for the booster heater. Over 10 idle hours a day that costs about $627 a year at $0.17/kWh.
Does the Meiko USA FV250.2 need a booster heater?
Yes. Hot-water sanitizing needs a booster to raise 140 °F building water to the final-rinse temperature. The certification data does not show an inseparable built-in booster for this model, so confirm with the specification sheet whether one is included or must be purchased separately.
How often should a Meiko USA dishwasher be delimed?
Delime whenever white scale appears on heating elements, the tank walls or spray nozzles — weekly in hard-water areas, less often with softened water. Use the manufacturer-approved delimer, rinse thoroughly, and never let it contact chlorine sanitizer.
