Bosch, a German company headquartered in Gerlingen, Germany, produces consumer appliances, including dishwashers. It specializes in high-end dishwashers, including ones with concealed controls and custom panels. While not common, a Bosch dishwasher sometimes has problems adequately drying dishes. You can often fix this problem without any additional help from a repair person. This saves you money on service fees.
Not Drying Adequately
If your Bosch dishwasher isn't drying correctly, see if you selected a heated drying setting. If you select an air-dry setting, your dishes may not completely dry. The Bosch "Rinse and Hold" cycle does not have a drying setting. Plasticware and Teflon dishes normally don't completely dry. Use a rinse aid to assist with the drying process. Do not overload the dishwasher, as this extends the drying time.
Your dishes will not dry properly if your power is interrupted. Verify that the dishwasher is connected to a power supply, and test the outlet with another appliance. Fully insert the power cord into the outlet. Check the household fuses or circuit breakers. Reset the circuit breakers if either is tripped. Examine the fuses to see if any are burned out. A burned out fuse usually has broken wires, or it's black. Replace the fuse.
The heating element is located on the bottom of your Bosch dishwasher. This element is responsible for heating up your dishwasher during the drying cycle so your dishes dry. If the element is not working properly, your dishes won't dry. Disconnect the dishwasher from the power supply and take out the bottom rack. Examine the heating element. A burned out heating element usually has black or white spots on it, or sections of it are cracked. Contact a Bosch parts dealer to order a new heating element. You can't usually repair these components.
The drying fan moves air around your dishes to speed the drying process. If the fan isn't working properly, your dishes may not completely dry. Unplug the dishwasher from the power source and remove the main housing. Examine the fan to see if it moves freely. Check the fan blades to see if any are broken. If the fan doesn't move or has broken components, replace it since it's difficult to fix.
The thermostat is responsible for the drying temperature. If the thermostat isn't working, the heating element won't kick on. Since the thermostat usually can't be fixed, replace it instead.
