Disassembly, Repair & Replacement

Note:

The unit should only be powered when it is in the upright position. Operation with the tank

tilted at an extreme angle can cause the tilt shutoff sensor to actuate, shutting off the heater.

Note:

Before beginning any repair, be sure to disconnect the sink from the power source.

Access to internal components is gained by removing the spout guide and the sink chassis.

Spout guide removal 

(Figures L1 & L2)

Tools: 

Channel lock pliers and 8 in.

crescent wrench.

1. Loosen the 1.75 in. hex nut at the base of

the spout guide.

2. Remove the spout guide from the heating

tank by wrenching on the hex fitting at the

top of the guide. Note: If using the optional

15-inch spout, wrench on the flats on the

sides of the pivotal spout guide.

3. Lift the spout assembly out of the tank.
4. Replace by reversing steps.

Chassis removal 

(Figure M)

Tools:

1/8 hex drive or Allen wrench and 

a 5/16 open-face wrench or crescent wrench

5.  Loosen  the  eight  screws  located  around  the  perimeter  of  the  sink

chassis.

6. Lift the sink chassis and locate the chassis ground lead and L.E.D.

wiring. Remove L.E.D. wiring connector from the control board. If

necessary, remove the ground lead from the sink chassis. 

7. Reassemble by reversing steps.
Once the interior of the sink has been accessed the following services can be performed:

Replacing fuses 

The control board and heating element are protected by the 15A

fuse and the pump is protected by the 2A fuse. Both these fuses are

located  on  a  bracket  atop  the  solenoid  valve.  The  fuses  are  not

intended to be operator replaceable. A blown fuse is a symptom of

a more serious problem with one of the parent components. Inspect

the appropriate system elements before replacing fuses.

Replacing the heating element

Tools:

Phillips screwdriver, 8 in. crescent wrench, and 1/8 hex

drive or Allen wrench

1.  Disconnect  the  heater  ground  and  power  leads  at  the

heating element. 

2. Loosen the hardware securing the heating element to the tank.
3. Pull the heating element from the tank.
4. If additional clearance is required, loosen the 4 screws on

the  underside  of  the  chassis  which  secure  the  pump

bracket. Apply a 1/4-inch bead of RTV sealant around the

heater  slot,  removing  old  sealant  if  necessary.  Replace

heater  by  reversing  the  disassembly  steps. 

Note:

The

attachment of the power leads to the heating element does

not require a specific wire orientation.
