Trouble Shooting The E.i. 600 If Not Producing Ice - Dometic Eskimo Ice 600 Installation & Owner's Manual

Trouble shooting the E.I. 600 if not producing ice

1. Check to see if power is reaching the ice machine. If raw water pump is running, power is
reaching the machine. If power light on temperature control is on, power is reaching ice
machine.
2. Check to see that on/off switch is in the "on" position. (see drawing #3)
3. Check high pressure control reset button on top center of control box. See drawing #3.
There are two reasons for high button to trip out.
A. Any time raw water pump has malfunctioned or is not circulating enough water, this reset
button has probably popped out. Push in to reset. Reset buttons should be pushed in (even if
they do not appear to be popped out). Start machine and check overboard discharge of water
during one minute delay before compressor starts. If no water is discharging see problem 5
below.
B. If the high pressure button trips out approximately 5 seconds after compressor starts, the
problem is not related to raw water cooling but is a problem with machine being overcharged
with refrigerant. To correct this problem turn machine off and recover a small amount of refrigerant
through the low pressure schrader valve. You may need to repeat this step two or three times
until fast tripping stops.
4. Check low pressure control reset button (located to left of high side button). Push in if out.
There are three reasons for low tripping.
A. If low pressure control trips after five to ten minutes of running the problem may be
improper vent hole in ice hose. See installation instructions (Ice hose installation detail).
B. If low pressure control continues to trip over and over on cold start up and raw water
temperature is 55° or lower it may be necessary to reduce water flow though water cooled
condenser to get the machine started. As water temperature warms up it will be necessary to
increase flow to full pump volume.
C. Low trips one to two minutes after machine starts. Machine may be low on refrigerant.
Check frost line as described on third page of trouble shooting.
5. Check overboard discharge of raw water. If not pumping, check to see if pump is running.
If you hear pump running but it is not pumping water overboard, check for air locks in hook
up hoses. (Hose must run uphill all the way from sea cock to overboard through hull) See
RAW WATER PUMP INSTALLATION INFORMATION PAGE with drawings.
6. Check ice delivery spout switch on ice machine. This switch is located on top of the
machine at base of stainless steel elbow from which the ice is pushed. It has two red wires
attached, one at the top and one at the bottom. If temperature control has malfunctioned and
ice has backed up delivery hose to machine, it will trip spout switch. Push to see if it will
reset. (See drawing #7) If spout switch trips repeatedly temperature control needs adjustment.
See start up procedure #5 and trouble shooting #10. The spout switch will also trip if there are
restrictions in the ice delivery hose. If hoses have been improperly installed in the ice selector
valve, the spout switch will also trip (see installation instruction on installing the ice valve).
