A slight water leak from your Bosch Pressure Washer is permissible. However, in case of an excessive leak, contact a service center.
Why does my Bosch AQT 35-12 motor keep stopping?
If your Bosch Pressure Washer motor stops unexpectedly, check the fuse and replace it if faulty. Ensure that the mains voltage matches the specifications on the model tag. Also, the motor protector may have activated; allow the unit to cool down for 15 minutes.
Why won't my Bosch AQT 35-12 motor start?
If your Bosch Pressure Washer motor refuses to start, first, ensure the plug is properly connected. If it is, try using another mains socket, as the current one may be faulty. Also, check the fuse and replace it if necessary. Damaged extension cables can also cause this issue, so try operating the pressure washer without one. If the motor protector has activated, allow the unit to cool for 15 minutes. Finally, check for freezing in the pump, water supply hose, or accessories and allow them to thaw.
What causes my Bosch Pressure Washer motor to stop?
If your Bosch Pressure Washer motor stops, it could be due to: * A faulty or blown fuse. Replace the fuse. * An incorrect mains voltage. Check that the mains voltage matches the specifications on the model tag. * The motor protector activating. Allow the unit to cool for 15 minutes.
What to do if my Bosch AQT 35-12 Pressure Washer pressure is pulsating?
Pulsating pressure in your Bosch Pressure Washer can be due to several reasons. First, air might be trapped in the inlet water supply; run the pressure washer with the spray handle open at low pressure until it stabilizes. Check that your water supply meets the specifications, with a minimum hose diameter of 1/2" or 13 mm. Clean the water filter if it's blocked. Ensure water supply hoses aren't squeezed. If you're using a high-pressure extension hose, remove it and retry, as the maximum length is 7 m.
Why does my Bosch Pressure Washer motor sound but fail to start?
If your Bosch Pressure Washer motor sounds like it's trying to start but fails, it could be due to: * Insufficient power supply. Verify that the voltage of the mains power supply line matches what's on the plate. * Voltage loss from using an extension cable. Check the specifications of the extension cable.
Why is my Bosch AQT 35-12 not taking in detergent?
If your Bosch Pressure Washer isn't taking in detergent, consider these possibilities: * The adjustable nozzle might be on a high-pressure foam setting. Attach the High-Pressure Foam nozzle or select the appropriate setting on the 3-in-1 nozzle. * The detergent may be too dense. Dilute it with water. * A high-pressure hose extension might be in use. Fit the original hose. * There could be deposits or a restriction in the detergent circuit. Flush it with clean water and eliminate any restrictions.
What causes low but steady pressure in my Bosch AQT 35-12 Pressure Washer?
If the pressure on your Bosch Pressure Washer is too low but steady, the issue could be: * A worn nozzle. Change the nozzle. * A worn start/stop valve. Activate the trigger five times in quick succession.
