Step 1: Fill the Fresh-Water Tank

Fill the fresh-water tank with enough clean water.

Check the water level through the tank’s water-level indicator tube. Make sure the water level is above the marked line shown in the picture below.

WARNING:

If the water level in the fresh-water tank does not reach the required level, the newly installed fresh

water level sensor may be damaged.

Step 2: Remove the Existing Sensor

Using a wrench, remove the existing fresh-water level sensor at the location indicated by the arrow in the picture below.

Step 3: Disconnect and Replace the Wiring

At the location shown in the picture below, cut the two wires connected to the original fresh-water level sensor.

Cut the wires on the new sensor at approximately the same location.

Remove the old sensor and replace it with the new one. Then connect the two wires from the new sensor

to the machine’s existing wires.

Make sure the wire connections are secure.

Step 4: Install the New Sensor

Install the new fresh-water level sensor in the same position as the original sensor, as shown in the picture below.

IMPORTANT:

Make sure the upward arrow on the sensor is pointing UP when installing the sensor.

How the Sensor Works

When There Is Enough Fresh Water

When there is enough fresh water in the tank, the fresh-water level sensor is closed. In this condition, the machine will not beep.

When the Fresh-Water Tank Is Empty

When the fresh-water tank is low or out of water, the sensor is open.

In this condition, the machine will continue to beep to remind the operator to add fresh water.
