HOW TO REPLACE WATER-VALVE - BOSCH DISHWASHER

BOSCH – SIEMENS – GAGGENAU – THERMADOR - DISHWASHERS - WATER-VALVE REPLACEMENT.

Dishwashers are rated 120V, 60 Hz, 15A, 1450W (max.). Maximum amp draw when heaters running ~ 11A.

TO ACCESS THE WATER-VALVE

> Remove two (2) T-20 Torx screws from toe kick and tilt toe kick out from under dishwasher.
> Remove base insulation (on models with insulation).
> Move sump inlet hose away from water valve (without disconnecting it).
> Disconnect wires from water valve, including ground wire.
> Remove two (2) T-20 Torxscrews from water valve.
> Pull valve out from dishwasher and disconnect water hose from rear of valve. Remove any water from sump & base.

HINTS

Water connection 3/8” NPT female. Inlet water pressure range 5 - 120 psi (0.3 – 8.27 bars).

Water valves have been upgraded several times since 1st 1/4 of 1999.

* 607335“Rast 5” time-fill water valve (UC/43 & above dw’s) has a keyed terminal connector and can’t replace 425458 or189533 valves. It replaces all “Rast 5” time-fill or pressure-fill valves.

* Time-fill valve #425458(UC/42 & below) also replaces pressure-fill valve #
189533. It looks like pressure-fill valve #189533, but isn’t the same. Pressure-fill valves can’t replace time-fill valves.

* Pressure-fill valve (part #189533) has a horizontally mounted solenoid and water fitting held in place by the metal mounting bracket. It replaced older pressure-fill valves (580009&167081) until time-fill valve425458was used.

When reconnecting the water supply to the water valve, don’t over tighten the elbow fitting. On valves with vertical solenoids, the plastic can crack and cause leaking if excessive force is used. • Using Teflon tape on water fittings can help prevent leaking. • The water valve can be accessed without removing outer door or base cover. However, removing them will provide easier access.
