Dometic 3100 Manuel D’Utilisation

10

In the event of an electrical failure, the flush ball can be manually operated to clear the bowl. We recommend using 

a long-neck screwdriver or 7/16-in. socket for the operation shown below. NEVER PRY OPEN THE FLUSH BALL 

FROM INSIDE THE TOILET BOWL. Damage to the flush ball and bowl seals may result.

2. Locate hole on left side 

of china toilet. This al-

lows access to the flush 

valve motor drive arm.

3. Insert screwdriver or  

7/16-in. socket through 

access hole and onto hex 

head.

4. Turn screwdriver or  

socket wrench 

clockwise. This will open 

flush ball and allow bowl 

contents to clear. After 

bowl is clear, turn screwdriver or socket wrench clockwise 

to return flush ball to original position.

1. Remove PC board  

access cover. Place 

Mode Switch in the 

“Manual Override” posi-

tion. This disconnects 

flush valve motor brake 

from electrical circuit.

NOTES:
Water will not enter the toilet bowl during manual flush 

operation.
Place Mode Switch in the “Normal” position before 

returning to automatic operation.
