What 003
actually means.

Hot-water sanitizing LXn models heat the final rinse in a small booster tank. If the booster has not reached its setpoint by the end of the fill, the screen shows Booster temperature not reached during fill cycle with 003. It clears with ENTER, but the next racks may not see a sanitizing rinse.

What to do when 003 shows on the commercial appliance

Kind of codeTemperature and alarms

The controller has seen a temperature outside the band it was set for and is saying so: a box above its alarm point, a fryer vat or an oven cavity that tripped its high-limit, or a dish machine rinse that never came up to heat. Often the cause sits outside the unit, such as a door left open during a delivery, a coil packed with grease, a kitchen far hotter than the maker allows or a booster fed cold water. Checking the door, the coil and the air around the unit is fair; move the product if a cold box stays above 41°F, and book the visit.

Reach-ins, pass-throughs, prep tables and blast chillers: gaskets, hinges, fans, thermostats, condensers and compressors.

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.

A Hobart dish machine that stops holding its rinse heat is usually seen right after the lunch racks clear, so the tank can drain and cool.

Before you book,
in this order.

Each step comes from Hobart's own guidance for 003 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.

01

Press ENTER to clear the message and watch the rinse temperature on the next cycle.

02

Check that the incoming water is as warm as the model requires; LXnH models expect about 110°F at the supply.

03

Hold racks until the display shows a rinse of 180°F, or sanitize another way your health code accepts.

04

Book a visit if 003 returns, since the booster element, its contactor or its sensor needs testing.

Still there?

It usually turns into reach-in and prep table repair. Book with the code and the model number.

What not to do

003 is not the booster overheating; that is 001 or the overtemp code 086. It is also different from 004, which reports the same slow booster during the wash rather than the fill.

Questions
about 003.

Can I clear 003 myself?
Press ENTER to clear the message and watch the rinse temperature on the next cycle. If it comes back, it needs a visit.
Can I keep washing on a Hobart that shows 003?
You can clear it and run, but check the rinse temperature on each cycle. If the final rinse stays below 180°F on a hot-water sanitizing model, the dishes are not sanitized to the standard the inspector will ask about.
Why does my Hobart show 003 in the morning only?
The first fill starts from the coldest water of the day, so a weak booster falls behind then and catches up later. That pattern still points to a booster that needs testing.
Does cold incoming water cause 003 on a Hobart LXn?
It can. The LXnH booster adds about 70°F, so it relies on a warm supply; LXnR and LXGnR models are built for cold water with an energy recovery unit.

Back to your everyday

Still showing 003?

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.
