5)If water pumps out properly and DP then de-energizes, proceed to step 6. If water does not pump out properly and/or DP does not de-energize, follow the steps below to prime DP.

Priming Instructions

a.Disconnect the icemaker's power cord from the electrical outlet, then reconnect to the electrical outlet. WARNING! To reduce the risk of electric shock, do not touch the power cord with damp hands.

b.Slowly pour another 16 to 24 oz. (500 to 750 ml) of water over the storage bin drain hole in the storage bin. If not already energized, DP should energize.

c.Confirm that water is discharged through the discharge hose. DP should then

de‑energize. If not, repeat steps a through c until water is discharged through the discharge hose and DP de‑energizes. DP is primed when DP de-energizes.

d. If water now pumps out properly and DP de-energizes, proceed to step 6. If water still does not pump out properly and/or DP does not de‑energize, follow the steps in "IV.E.3. Float Switch Cleaning" before proceeding.

6)Move the power switch to the "ON" position.

7)Pour another 16 to 24 oz. (500 to 750 ml) of water into the icemaker's ice storage bin, then completely restrict the discharge hose while DP is operating. See Fig. 7. Pour more water into the icemaker's ice storage bin until the icemaker turns off. DP will continue to operate. Check for leaks.

8)Remove the discharge hose restriction and allow the water to be pumped out normally. Power to the icemaker will be restored when the water in DP returns to a normal level.

9)If the icemaker fails to turn off with the discharge hose restricted or the pump fails to pump out the water, follow the steps in "IV.E.3. Float Switch Cleaning".
