Test strip-water hardness

About This Part

# Test Strip - Water Hardness for Bosch Dishwashers If your dishwasher isn't cleaning dishes properly or leaving spots and residue, the water hardness test strip may have worn out or failed. This small but essential component helps your Bosch dishwasher detect your local water hardness levels, allowing it to adjust detergent dosing accordingly. Without a functioning test strip, your machine can't optimise its cleaning performance. The test strip gradually deteriorates through regular use and exposure to water. When it fails, your dishwasher struggles to deliver the right balance of wash performance and efficiency. Replacing it (OEM reference 00629757) is a straightforward task that most DIY homeowners can manage in minutes. Installation difficulty is minimal, rated at level 2. Our practical tip: before removing the old strip, note its position carefully so you can reinstall the replacement exactly the same way. This ensures proper sensor readings and optimal dishwasher performance going forward. This part is compatible with a range of Bosch dishwasher models. Before ordering, please verify your appliance's E-Nr model number to confirm compatibility with this component.
