Bosch Dishwasher SHV4803 UC/07 Parts

The Detergent Dispenser Assembly is an OEM part for Bosch dishwashers.  The detergent dispenser assembly works with the control system to release detergent during the wash cycle.  

Causes of a bad detergent dispenser assembly can include broken or loose mounting points, a dispenser that no longer locks into place, or a damaged latch mechanism preventing the dispenser from opening.

Symptoms of a bad detergent dispenser assembly include:

• Detergent not dispensing or distributing as intended
• Dispenser door unable to close or remains open
• Excess clutter inside the dishwasher
• Ineffective cleaning or dirty dishes after cycles

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

The Drain Pump Cover is an OEM part for Bosch dishwashers. This cover protects the drain pump mechanism from debris while draining dirty water after each cycle.

Causes of a bad drain pump cover include cracks or breaks from heavy impacts over time.

Symptoms of an improperly functioning cover include:

• Leaks in the area around the drain pump
• Decreased drain and pump performance over time
• Potential clogs from broken pieces inside

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

The Upper Spray Arm Water Tube is an OEM part for Bosch dishwashers. It is a vital component of the washing mechanism responsible for spraying water across the upper rack. 

Over time, mineral deposits can clog the narrow openings of the water tube, reducing water pressure and spray effectiveness. Accidental bending or cracking of the flexible water tube could also cause spray issues.

Symptoms of a bad upper spray arm and water tube include: 

• Incomplete cleaning of dishes on the upper rack
• Dried food soils left behind after washing  
• Noticeably weaker water spray pressure from the arm
• Possible leaks or drips around the arm connection point

Replacing with this OEM Bosch part restores full spray coverage and optimized washing for all rack levels. It is also compatible with certain Miele, Asko, and Jenn-Air professional-grade dishwashers.
 

This upper trim strip finishes the top edge of the appliance's front opening, restoring a clean look and helping protect nearby components. Replace a cracked, missing, or loose strip to keep panels aligned and secure.

• Provides a finished edge along the upper portion of the door/face area
• Helps protect adjacent components from dust and minor splashes
• Maintains proper panel gaps and alignment
• Typical symptoms: visible cracks, warping, looseness, rattling, or exposed/sharp edges

• Disconnect power before servicing; also shut off water
• Remove the existing strip by releasing screws/clips; retain hardware for reuse
• Align the new strip and secure evenly—do not overtighten fasteners
• Check door/panel operation afterward to confirm proper fit and clearance

This O-ring is the sealing gasket between mating components, keeping fluid contained inside the system. Replacing a worn ring restores a tight, leak-free connection and helps prevent drips, moisture, and leak-related error indications.

• Creates a compressible seal between parts to prevent leaks at the joint
• Helps maintain proper system flow by stopping seepage or air ingress
• Direct replacement for rings that are flattened, cracked, brittle, swollen, or missing
• Common symptoms include dripping at the connection, moisture beneath the unit, or leak/float error alerts

• Disconnect power and shut off the water supply before servicing; wear appropriate PPE.
• Note the original ring's location; clean the groove and mating surfaces before installation.
• Apply a light coat of compatible silicone grease; avoid twisting or overstretching the ring.
• Seat evenly, reassemble, restore service, and check for leaks during a test cycle.

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 sump screw secures the dishwasher's sump or sump cover to the tub, keeping the assembly tight and leak-resistant. Replace a missing, stripped, or damaged screw to restore a proper seal and stable mounting.

• Fastens the sump or sump cover to the dishwasher tub
• Helps maintain a watertight seal to reduce leaks
• Keeps filter/sump components aligned and secure
• Replaces missing, stripped, or damaged hardware
• Helps address leaks or rattling around the sump area

• Disconnect power and turn off water supply before servicing
• Remove the lower rack and filters to access the sump area
• Ensure mating surfaces and seals are clean and properly seated
• Tighten snugly by hand; do not overtighten to avoid stripping

Includes door latch, strike plate and microswitch.

The Float is an OEM part for Bosch dishwashers. This float senses water levels inside the dishwasher, signaling the inlet valve to refill when needed.

Causes of a float malfunctioning can be mineral deposits accumulating and weighing it down over time, or cracks in the plastic housing allowing water in.

Symptoms of a bad float include:

• The dishwasher not filling or filling slowly
• Error codes related to fill issues
• Improper water levels impacting wash results

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

Color: gray. Each clip measures about an inch and each pack includes 2 clips.
