Flush the toilet again. If the bowl unit is not cleansed with a flushing, 
remove the stains with a brush or similar instrument.

29

 

When the tank is 

fi

 lling, you cannot 

fl

 ush the toilet.

 

Once the "Power" LED on the main display are lit and the tank fills up with 
water, flush the toilet.

-

A small amount of 

water 

fl

 ows into the 

bowl unit after the unit 

fl

 ushes

 

If the water supply pressure drops signi

fi

 cantly, for example if water is used 

elsewhere or if there is a water failure, water is supplied so that the water 
surface in the bowl unit rises to a certain level.
If the same symptom reappears. 

 There may be a malfunction.

Consult with TOTO customer service (see contact information on the back cover).

Some barium remains 

after 

fl

 ushing

 

It may be dif

fi

 cult to 

fl

 ush down substances with a higher speci

fi

 c gravity than 

water, such as barium.

 

Flush the toilet again. If the bowl unit is not cleansed by flushing, remove 
the stains with a brush or similar instrument.

29

There is residue on 

the bowl unit surface

 

Oil and other hard-to-see grime may stick to the bowl unit surface.

 

Clean with (non-abrasive) neutral toilet detergent.

29

Pulling the hand lever 

(for 

fl

 ushing in case 

of power outage) 

does not 

fl

 ush 

the toilet

 

Pulling the hand lever does not 

fl

 ush the toilet when the power is supplied.

When testing the operation, unplug the power plug.

 

To 

fl

 ush the toilet with the hand lever, keep pulling the lever until the beep 

sound is made and water supply stops.

 

You cannot 

fl

 ush the toilet for about 60 seconds after 

fl

 ushing it with the hand 

lever or releasing the hand lever halfway.

 

Wait at least about 60 seconds and then flush the toilet again.

 

If power outage lasts for a long period (2 days or more), insert batteries in the 
battery box.

 

If the toilet does not 

fl

 ush with batteries in the battery box, the batteries are 

running out.

 

Replace them with new ones.
