The Affresh Dishwasher Cleaner is an OEM accessory designed specifically for Whirlpool brand dishwashers. This citrus-scented tablet removes residue, odor-causing soils, and food particles from the dishwasher tub and gasket area during the cleaning cycle. Symptoms of a buildup include unwanted odors emanating from the dishwasher, especially after opening the door. Over time, residue and grime accumulate in hard-to-reach areas and provide an environment for mold and mildew growth.

Regular cleaning helps prevent this by removing leftover soils before they harden or encourage bacterial activity. The Affresh tablet utilizes a unique blend of cleaning ingredients that target soils and biofilms through a combination of powerful scrubbing action and natural cleaning enzymes.

As the #1 recommended dishwasher cleaner brand, Affresh is also compatible for use in Maytag, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and select Kenmore dishwashers for consistent cleanliness and freshness. The package includes six tablets 4.2 ounces

NTC (negative temperature coefficient). Resistance or capacitance decreases when temperature increases.

The Temperature Sensor with Hi Limit Thermistor is an OEM part for Bosch dishwashers. This sensor monitors internal temperatures, providing feedback to the control module during each cycle.

Causes of failure can be related to mineral buildup over time interfering with sensing or physical damage to wiring or connectors.

Symptoms of a bad temperature sensor include:

• Abnormal or inconsistent wash temperatures
• Error codes related to temperature issues
• Reduced cleaning performance from improper heating

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

This O-ring seals the NTC (negative temperature coefficient) temperature sensor where it inserts into the appliance. It restores a watertight seal at the sensor port to help prevent leaks and maintain reliable temperature-sensing performance.

• Provides a leak-tight seal between the NTC temperature sensor and its housing/tub/sump
• Helps prevent water seepage and moisture intrusion around the sensor opening

• Clean and inspect mating surfaces; replace any damaged components
• Lightly lubricate the O-ring with approved silicone lubricant, seat evenly without twisting, and test for leaks after reassembly

This turbidity sensor detects how clear the dishwasher's wash water is so the control can adjust cycle time, rinses, and water changes. Replacing a faulty sensor helps restore proper cleaning performance and normal cycle lengths.

• Monitors soil level/clarity of the wash water
• Signals the control to extend or shorten wash and rinse phases as needed
• Helps optimize water use while maintaining cleaning results
• Failure symptoms can include unusually long or short cycles, poor cleaning, repeated draining/refilling, or cycles that won't advance

• Disconnect power and turn off the water supply before servicing
• Pull the dishwasher out as needed; access the sensor from the base area
• Place a towel to catch residual water; release the locking tab or twist-lock, unplug the connector, and install the new sensor fully seated and locked
• Restore power/water and run a test cycle; check for leaks

Small replacement O-ring that seals the dishwasher aqua sensor assembly to maintain a watertight seal and help ensure reliable sensor operation. Fits the sensor housing to reduce leaks and protect internal electronics. What it does:

• Seals the aqua/sensor housing to prevent water from escaping the sensor area
• Helps maintain accurate sensor readings by keeping the sensor dry and properly seated
• Commonly replaced when you see water pooling or dripping near the sensor assembly
• Used during aqua-sensor, pump, or housing repairs where the original seal is damaged

• Always disconnect power and turn off the water supply before starting repairs
• Replace the O-ring only when the sensor or housing is disassembled; inspect mating surfaces for damage or debris
• Ensure the O-ring is seated evenly in its groove before reassembly to avoid pinching or leaks

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

The Float Switch is an OEM replacement part specific to Bosch dishwashers. It is a switch located in the sump area of the dishwasher tub that detects water levels and provides feedback for automatic filling and draining functions.

Symptoms of a bad float switch include:

• The dishwasher fails to fully drain water after cycles
• Cycles not initiating or advancing properly due to water level issues
• Float switch area where the sensor attaches developing leaks
• Loose or detached float switch from normal wear over time

Causes of a bad float switch are usually mineral or sediment buildup disrupting its buoyancy and sensing ability. Without a properly functioning float switch, the dishwasher cannot effectively monitor water levels to manage filling and drainage.

This OEM Bosch replacement switch is also compatible with Thermador, Gaggenau, and some Kenmore dishwasher models.

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 Sump to Water Inlet Hose is an OEM replacement part for Bosch dishwashers. It efficiently transports water from the internal sump to the dishwasher's inlet valve during wash cycles. The flex hose comes with 2 o-rings. Approximate size: 19 5/8 inch.

Symptoms of a faulty sump hose include:

• Incomplete or ineffective washing from insufficient water transfer
• Hoses detaching from connections allow water to spill
• Reduced water pressure signs like slower fills or weak sprays
• Leakage where the hose connects to other components

Over many uses, mineral deposits can build inside the hose restricting flow. Physical damage like cracks or kinks also inhibits proper drainage. Replace your hose with this genuine Bosch part to restore maximal washing capacity.

Compatible with Thermador, Gaggenau, and some Kenmore models utilizing the same hose dimensions, this OEM hose ensures washing needs are consistently met.

The Drain Hose is an OEM part for Bosch dishwashers, designed to facilitate the efficient and reliable expulsion of wastewater from the appliance to the household drainage system.
