What 021
actually means.
At the end of a drain cycle the LXn checks the tank level. If a lot of water is still there, the screen reads Drain hose is clogged with 021. Hobart's first steps are a clear tank bottom and a straight, clean drain hose.

What to do when 021 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.

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 021 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Switch the machine off and let the wash water cool.
Clear any debris from the bottom of the tank and around the strainer.
Follow the drain hose from the back of the machine and straighten any kink or low loop where grease can settle.
Run the drain again; water that still will not leave points to the drain pump, which is a service item.
What not to do
021 is not a blocked strainer; that is 019. It is also different from 022, which catches a water level that drops during the wash rather than water left after draining.

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.
