STEP THREE: Clean theTank
Use tap water to flush loose minerals from the tank:
• Sediment screen at tank's bottom is removable.
For a more thorough cleaning, soak tank in water
with CLR ®, LimeAway ® or white vinegar. Then
rinse clean.
Tank is dishwasher safe.
Do not use hydrocarbon-based cleaners.
Unplug the power cord and carefully rub minerals
off of the heating element and tank walls. Clear the
sensor compartment holes of debris, if present.
STEP FOUR: Replace the Water Level Sensor (if necessary)
Remove TrueSTEAM cover and inspect water
level sensor. If debris buildup is present, replace
the sensor (see below).
Remove T-30 Torx screw and lift clamp.
Remove the sensor.
Ensure sensor gaskets are seated properly and are in
good condition (no cracks).
Install a new sensor if excessive mineral deposits are
present, or if gaskets are in poor condition. See "Parts
List" on page 35.
