If your Bosch dishwasher stops after running for only 3 minutes, there could be several potential reasons for this issue. Here are some common causes to consider:
Water supply issues: Check if the dishwasher is receiving an adequate supply of water. If there is a problem with the water inlet valve or a blockage in the water supply line, it may not be able to fill up properly, causing it to stop.
Door latch problems: A faulty door latch or door switch can prevent the dishwasher from running a full cycle. If the door is not securely closed, the dishwasher may stop to avoid any potential water leakage.
Drainage problems: If the dishwasher detects a problem with draining water properly, it may stop to prevent any overflow or damage. Check for clogs in the drain pump, drain hose, or garbage disposal connection.
Heating element issues: A malfunctioning heating element may cause the dishwasher to stop because it cannot achieve the necessary water temperature for certain cycles.
Control board or timer malfunction: Problems with the dishwasher's control board or timer can lead to improper functioning, including stopping the cycle prematurely.
Overloaded or improperly loaded dishwasher: If the dishwasher is overloaded or items are blocking the spray arms, it may stop as a safety measure to avoid damage.
To troubleshoot the issue, you can try the following steps:
Check the water supply and ensure it is sufficient and not blocked.
Verify that the door is closing properly and latching securely.
Inspect and clean the drain filter, pump, and hose for any obstructions.
Run a diagnostic cycle (if available) to see if any error codes are displayed.
If you are unable to identify the problem or resolve the issue on your own, it is recommended to contact Bosch customer support or a qualified appliance repair technician to diagnose and fix the problem. Do not attempt to disassemble or repair the dishwasher yourself if you are not experienced in appliance repair, as it can be dangerous and void the warranty.
