I can provide some general information regarding Bosch washing machines.
Water Pressure: The required water pressure for a Bosch washing machine typically falls within the range of 1 to 10 bars (14.5 to 145 psi). Washing machines are designed to function effectively within this pressure range. It's important to note that very low water pressure can lead to extended washing times, and very high water pressure can potentially damage the machine or cause leaks. Consult the specific model's user manual or check the product specifications on the Bosch website for the precise water pressure requirements for your washing machine.
Minimum Height of the Tank: It's unclear what you are referring to by "tank" in this context. If you are referring to the water supply tank, the height of the tank doesn't typically have a direct impact on the washing machine's performance. However, the water supply tank should be positioned at a sufficient height to ensure that water flows to the machine using gravity. Generally, it is recommended to place the water supply tank at least a few feet above the washing machine inlet to facilitate proper water flow.
To get the most accurate and up-to-date information for a specific Bosch washing machine model, I recommend referring to the user manual that came with the appliance or checking Bosch's official website for detailed specifications.
