Possible EE display. 2. Low supply line pressure.
3. Excessive mineral deposits throughout wash and rinse system. Deliming may
be necessary, refer to page 20.
4. Incoming water temperature to booster (if applicable) below 110°F. Machine
will automatically extend wash time until booster heats up (this applies to
booster equipped machines only).
5. If EE displays: Booster did not reach temperature within 8 minutes after initial
fill. Press OFF, wait 5 seconds and press ON. May be booster heater failure.

if the water level drops. Check for proper water level. If the water level is
too low, the overflow tube might be out of position. Or, something may be
inhibiting free movement of the low water float; remove any foreign object from
around the low water float or its magnet.
2. Gas line closed.
3. Blown fuse or tripped circuit breaker at power supply.
If a failure occurs due to the gas heat control board or gas pressure,
contact Hobart Service.

Possible Ed display. 1. Slow leak. Make sure the drain lever is closed, the standpipe is seated and
the O-ring is clear of all food soil or other debris.
Dribbling water from lower 1. If equipped with electric booster, normal dripping from the lower rinse arm
rinse arm. will occur during water heating due to expansion of the water. This will occur
