DIAGNOSTIC MESSAGES
In the event of a problem with a temperature probe, the display will flash "P1," "P2," or "P3" every 10
seconds. The respective heaters will shut down. Other functions will continue to operate normally.
Contact your local Hobart Service Office.
Drain and fill error messages are displayed as E0, E2, E3, E4, E5, E6, or E7. In all cases, the
dishwasher will terminate current cycle operations, turn off all heat sources, and display the message
until the OFF button is pressed. (A power drain will not occur when turned off.) (See Troubleshooting,
pages 26 – 28.) If problem persists, contact your local Hobart Service Office.
MODELS LX18, LX18C & LX18H
Models LX18, LX18C and LX18H can be programmed by Hobart Service as either "True Fill and Dump"
or "Modified Fill and Dump".
Modified Fill and Dump
When programmed for "Modified Fill and Dump", water in the sump from a previous cycle is dumped
and refilled only if it is below a preset temperature. Advantages: Low water usage if cycled frequently;
and, short cycle time if cycled frequently. Disadvantages: Higher water usage if cycled infrequently;
and, longer cycle time if cycled infrequently.
Modified Fill and Dump — WASH/RINSE CYCLE TIMES (Factory Default on LX18H)
Drain* 45 Sec. Max. 22 Sec. Typical
Fill* 65 Sec. Max. 40 Sec. Typical
Wash* 115/140 Sec.
Drain 45 Sec. Max. 22 Sec. Typical
Fill 65 Sec. Max. 40 Sec. Typical
Rinse 15 Sec.
* Drain and Fill only if the sump water temperature is below 160°F in LX18 or LX18H machines,
or 130°F in LX18C chemical sanitizing machines. The slower cycle will also have a
140 second wash instead of the 115 second wash.
True Fill and Dump
When programmed for "True Fill and Dump", the sump is empty at the start and end of a cycle.
Advantages: Consistent, short cycle time; and, will not dump manual detergent charge. Disadvantage:
Uses more water.
