I have a PD code on a Hobart LXI dishwasher. What does that mean

Probably the temperature sensor, but do you want to risk $227 on a guess? It is a commercial machine, just call your local service tech.

It is NOT a common fault

Question edited for a lot more clarity. All question need FULL 'make model (what it is)'.
Question moved from laundry Washing Machines to Hobart Dishwasher category.

'DP' or 'PD'?

PD is not an error code. It shows that when it draining water out shortly after power-up and when shutting down. If it seems to be showing "PD" longer than usual, it means the dishwasher's control circuitry believes there is still water in the tank, due to a faulty water level probe, most like the one under the lift-out screen. It has a plastic body with a metal probe coming out the center.

There is also a dual probe at the rear of the machine, but I believe the dishwasher uses the front probe to determine when to stop draining the machine during "PD" - most likely meaning "Power Drain" or "Power Draining".

If you are not seeing any E- codes (E1, E2, E3, etc.) then these water level probes are likely just fine and the "PD" is appearing normally, as it should during draining conditions.

Manual just for fun.

P3 code refers to the probe near the airgap at the back. It is monitoring the rinse temp. P2 is the booser probe, and P1 is the wash tank. The control board will store error codes, so once changed, you can access the memory and clear it.

Your local Hobart office.

Contact your local chemical supplier such as EcoLab or AutoChlor to purchase the proper chemicals. Use ONLY commercal dish washing chemicals. Residential detergents like Cascade do not dissolve fast enough and WILL, in time, cause you trouble if used in the LXi.

There should be three colored plastic tubes at the rear of your machine. Red is to be put in a container of liquid detergent, Blue is for rinse aid, and white/clear is for sanitizer. Your chemical salesman should be able to show you how it's done at no charge.

You may also want to register here http://www.hobartservice.com/Manuals/ then download the manuals for the LXi dish machine.

All the best.

The first thing you should do is clean the level probes in the unit. There are two probes sticking through the back of the unit and the water completes a circuit between these two telling the machine when it is full. If they are clean, you may have a faulty sensor or wiring.

I think you may have the wrong model number of the dishwasher.I work for hobart but i dont recall a dishwasher with the model number you givin me.Look on the data plate again some examples of hobart dishwashers are--sr24---am14---c44---c44a---lx18--lx30--lx40---lxi---uw50--sm6t2.Once you find the model goto this site and you will find a manual.any other questions let me know.http://www.hobartcorp.com/default.aspx
