Bosch Dishwasher SHV4803 UC/06 Parts

The Pressure Chamber is an OEM part for Bosch dishwashers. This part is responsible for monitoring and controlling the water level within the dishwasher. It operates by sensing the pressure exerted by the height of the water in the tub and ensures that the dishwasher fills with the correct amount of water for optimal cleaning performance.

Causes for replacement may involve wear and tear over extended use, mineral buildup affecting the switch’s sensitivity, or electrical faults leading to inconsistent performance.  

Symptoms of a failing Pressure Chamber include:

• Overfilling or underfilling of the dishwasher, which can lead to inadequate cleaning or potential water damage.
• Unexpected changes in the wash cycle, such as sudden stops or pauses.
• The dishwasher not starting a wash cycle due to incorrect water level readings.

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.

The Water Inlet System is an OEM component specifically designed for select Bosch dishwashers. Comprising inlet valve, screens, hoses, and connectors, it precisely meters fresh water. Reliable flow prevents mineral buildups from impairing performance.

Causes of a bad water inlet system commonly involve bursting hoses or stripped connectors. Prolonged pressure weakens seals requiring timely replacement.

Symptoms of a faulty water inlet system include: 

- Fluctuating or absent water flow to spray arms
- Leaks forming inside or near the installation site
- Errors relating to improper water temperature or amounts  

Causes of a bad water inlet system involve typical degradation such as:

• Limescale clogging narrow valve openings
• Plumbing joint corrosion compromising integrity
• Splitting plastic tubing unable to withstand cycles

This OEM Bosch part is also compatible with some Miele, Blomberg, and Thermador dishwashers.

This genuine OEM part is a circulation pump motor for dishwashers. The circulation pump motor distributes water to the spray arm to allow the dishwasher to properly do its job. Over time, the circulation pump motor can become overworked to the point of becoming inoperable. Luckily, replacing the pump motor is not as difficult a job as it might seem. To begin the repair, turn off the power supply and shut off the water supply valve. Remove the screws that secure the lower access panel. Disconnect the water supply line from the inlet valve. Then proceed to remove the mounting screws from the junction box cover. Take note of the wires' orientation. Remove the screws that hold the bracket. Disconnect the drain hose from the sink or garbage disposal. Open the dishwasher door and remove the mounting screws. Pull the dishwasher away from the cabinet and unsnap the covers from the hinge ropes. Disconnect the ropes. Remove the screws securing the upper door panel. Carefully tilt the dishwasher back and detach the fill hose from its retaining clip disconnecting the hose from the sump. Uninstall the circulation pump and align the pump with the seal and sump. Tighten the clamp and transfer the wires from the old pump to the new one. Proceed to reinstall the panels that were uninstalled.This replacement part is sold individually and is compatible with Bosch, Gaggenau, and Thermador dishwashers.
