If your Bosch dishwasher starts and then stops before it begins a cycle, it may indicate a few potential issues:
Door Latch Issue: One possibility is that the door latch is not engaging properly. The dishwasher has a safety mechanism that prevents it from running if the door is not securely closed. Check if the door is fully closed and latched. If the latch is loose or damaged, it may need adjustment or replacement.
Control Panel or Control Board Problem: Another potential cause is a malfunctioning control panel or control board. If there is a problem with the electronic controls, the dishwasher may start briefly and then shut off. Try resetting the dishwasher by turning off the power at the circuit breaker for a few minutes and then turning it back on. If the problem persists, it may require professional diagnosis and repair.
Water Supply Issue: A faulty water supply can also cause the dishwasher to start and stop. Check if the water supply valve is fully open and providing adequate water pressure. Inspect the water inlet hose for kinks or blockages that may restrict water flow. Additionally, ensure that the water inlet filter screen (located on the water inlet valve behind the kick plate) is clean and not clogged.
Blocked or Clogged Components: If there are obstructions in the dishwasher's components, such as the spray arms or filters, it may cause the dishwasher to stop. Inspect the spray arms to ensure they can rotate freely and that there are no debris or food particles blocking the spray nozzles. Clean the filters and remove any buildup that may restrict water flow.
Sensor or Safety Feature Activation: Some Bosch dishwashers have sensors or safety features that can interrupt the cycle under certain conditions. For example, if the dishwasher detects a leak or excessive suds, it may stop to prevent further damage. Check for any visible leaks or excessive suds and address them accordingly.
If you have checked these potential issues and the problem persists, it is advisable to consult the Bosch customer support or seek assistance from a qualified technician to diagnose and resolve the specific problem with your dishwasher.
