Symptom
Possible Causes
Leaking valve.
1. Foreign material preventing proper valve operation.
NOTE:
A critical period is soon
after installation when pipe compound or metal shavings may lodge at the valve
seat. Shut off supply line. Unscrew and lift bonnet from valve body. Clean valve
and reassemble.
2. If a solenoid valve is malfunctioning (not opening or not closing), it is recom mended
that you contact your local service provider.
No wash tank heat.
1. The machine is equipped with a low water safety device which shuts off heat 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. Blown fuse or tripped circuit breaker at power supply.
No or slow fill.
Possible E2 display.
1. Debris may be obstructing standpipe movement allowing fill water to drain.
2. Water supply may be off; make sure hot water supply valve is open.
3. Dirty line strainer causing reduced water flow. Turn off hot water supply, remove
strainer cap, withdraw and clean screen. Reassemble.
4. Worn or torn drain O-ring allowing wash water to drain.
5. If E2 displays: Water did not reach the float during a fill within 2.5 minutes. Press
OFF, wait 5 seconds and press ON.
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 rinse arm.
1. If equipped with electric booster, normal dripping from the lower rinse arm will
occur during water heating due to expansion of the water. This will occur once
between machine cycles.
