Water keeps overflowing out of the sump trey continue running

CM3 Operational Sequence.
From Off, push and release the freeze button.
1. If sump is full,water pump starts.If sump is not full,water valve opens to fill it.
2. Compressor starts when sump is full.Air cooled fan motor starts too.
3. water pump stops early in freeze cycle for 30 seconds.
4. Sump refills after pump starts.
5. In low ambient condition,fan motor may begin to cycle on and off.
6. Freeze continues until water level in sump drops to preset point. Exceptions: SCE275 must fill sump two more times.
7. Fan may shut off before the end of freeze.
8. Harvest begins. Hot gas valve opens,pump stops.
9. Pump restarts, inlet water valve opens to fill and overflow the reservoir.
10. Harvest continues for preset first cycle harvest time.
11. If bin is not full, cycle repeats ( compressor stays on). If bin is full, unit shuts off at the end of harvest.
OK with that out of the way unless you unplugged any wires cleaning the machine should not have caused any problems. First cut off water and pull water supply line from water inlet valve look in the end of valve there is a screen in there it could be stopped up. If the valve screen is not stopped up then put supply water line back on and turn water back on. power the CM3 controller off. push freeze button. now with a voltage meter check at the water inlet valve to make sure you are getting power to the valve.If you are then either valve is stopped up or valve is bad. If you are not getting power to valve then replace the CM3 controller now make sure the bin full light is not on because if it is this will not let controller go back to a freeze cycle.

where is the water running on the ice head or is this a remote water cooled condenser? If water is running all the time at the ice head into the sump tray and overflowing into the ice bin then check the water inlet valve ether rebuild or replace valve but make sure the water low sensor is not calling for water when the sump tray is full of water.

2 possibilities.1. The water level is set higher the the overflow tube. This will cause the water to run into the overflow continuously. You should be able to see this. 2. The large seal - bottom center of the tank - is leaking. This will cause the water level to slowly drop after a fill. The water tank will start to run again after flushing - BUT NOT CONTINUOUSLY. You should see if there is a small amount of water flowing from the rim to the bowl 15 seconds after the water has stopped running after a flush.

The drain in the freezer behind back lower panel
needs opening. You can see it at the bottom of the back panel
underneath the evaporator coils. (The cold coils)
Run Hot water in the drain until it clears or use a hairdryer.
When the defrost melts the water it goes down the drain
If the drain is clogged with Ice or ? The defrost water
overflows into the ref. or freezer or on floor
Run Hot water in the drain until it clears or use a hairdryer.
Also check fan undernearh Ref in the rear
Clean condenser coils underneath

You have a leak in the radiator, water pump, a hose, the heater or a head gasket. Check these and see if there is any water coming out of the exhaust or in the sump.
Take off the radiator cap, fill it right up to the neck, start the engine and warm it up. See if there are any bubbles in the top of the radiator, keep it topped up so there is no room in the top tank.
If there are continuous bubbles then there is a leak in the head gasket.

Do you mean that it is overflowing the sump tray into the bin? If so there are two things to check. First make sure the unit is level. Second their is a simple water float valve much like an old toilet float that keeps the sump full. Turn the machine off and make sure that the float will stop the water flow 100% when the sump water level is just over the bottom of the water pump impeller. If the float will not stop the water flow either the water pressure is too high or the float valve is bad and has to be replaced. In general water pressure should be between 20-40 psi.

Hi dear.If you are handy enough,that's what you can check to make a solution for yourself.Goodluck.
Check all hoses, connections and threaded unions for leaks.
Note:
If the leak source has not yet been detected, check the following areas
in the toekick and the drip pan for wear and tear:
�� Connection between the circulation pump and the sump
�� Axial face seal of the circulation pump
�� Connection between the drain pump and the sump
�� Connection between the salt container and the water intake
�� Connection between the water intake and the cabinet side wall
�� Overflow (e.g., excess foam formation)
�� Water level between the overflows (�� seating of the lower door seal?)
�� Connection between the cabinet and the salt container
�� Non-return valve in the sump (�� water running back from the drain hose?)
3. Check overflow float switch B8/3 for continuity and correct operation.
4. Carefully dry all electrical components in the drip pan area.
Cause:
Float switch defective.
Remedy:
Replace overflow float switch B8/3.
I hope that helps.Thanks.

Unit is functioning on the back up freeze timer.
Cause:
Float Switch stuck in the up position.=Empty sump, remove float switch (Carefully and watch the small pin that keeps the float inside). Clean and reassemble.
Water Valve leaking by:=Only fix is to replace. Turn unit off. If water continues to run in and overflows the sump, it's leaking.
The other things that can cause this requires a qualified tech as it is a refrigeration problem.

Hope this gets it for you.

Some diswashers have a sump in the bottom with a float switch. If the water level overflows the float will activate the switch which will kill the machine and run the drain pump continuously.
