What to do if my Bosch Pressure Washer motor sounds but fails to start?
If your Bosch Pressure Washer motor 'sounds' but doesn't start, it could be due to an insufficient power supply. Verify that the voltage of the mains power supply line matches what's indicated on the appliance plate. Also, check the characteristics of your extension cable, as voltage loss can occur when using one.
Why does my Bosch AQT 37-13 keep blowing fuses?
If your Bosch Pressure Washer keeps blowing fuses, the fuses may be incorrectly rated. Change to a mains supply higher than the pressure washer amp consumption.
What to do if my Bosch AQT 37-13 has low pressure?
If your Bosch Pressure Washer starts up but has restricted or no working pressure, first ensure that the water supply is connected. If it is, the water filter may be clogged; clean it. Also, the nozzle may be clogged; clean it as well.
Why is my Bosch Pressure Washer motor not starting?
Several factors can prevent your Bosch Pressure Washer motor from starting. Ensure the plug is properly connected. Try a different mains socket in case the current one is faulty. Replace the fuse if it's blown. Remove any extension cables to rule out damage there. The motor protector might have activated, so allow it to cool for 15 minutes. Lastly, check for freezing in the pump, water supply hose, or accessories; thaw if necessary.
How to fix pulsating pressure on a Bosch Pressure Washer?
If you notice pressure pulsating in your Bosch Pressure Washer, it might be due to air in the inlet water supply hose or pump. To resolve this, run the pressure washer with the spray handle open and the nozzle at low pressure until you achieve a regular working pressure. Also, ensure you have an adequate water supply, meeting the minimum specification of a 1/2" or 13 mm diameter hose. Check and clean the water filter if it's blocked, and straighten out any kinks in the water supply hoses. If you're using a high-pressure extension hose, remove it and retry, ensuring it doesn't exceed the maximum length of 7 meters.
Why is the pressure too low on my Bosch Pressure Washer, but steady?
If the pressure on your Bosch Pressure Washer is too low but steady, the nozzle may be worn. Try changing the nozzle. Another possibility is a worn start/stop valve. Try activating the trigger five times in quick succession.

Also, check that the water supply meets the specifications, with a minimum hose diameter of 1/2" or 13 mm. Clean the water filter if it's blocked, straighten any kinks in the water supply hoses, and if using a high-pressure extension hose, remove it and retry, ensuring it doesn't exceed 7 m.
What to do if my Bosch Pressure Washer motor stops?
If your Bosch Pressure Washer motor stops, several issues could be the cause. First, check the fuse and replace it if it's faulty. Next, ensure the mains voltage corresponds to the specifications on the model tag. Lastly, the motor protector might have been activated. If so, allow the pressure washer to cool down for 15 minutes before restarting.
Why is no detergent taken in by my Bosch AQT 37-13?
If your Bosch Pressure Washer isn't taking in detergent, make sure the adjustable nozzle isn't on a high-pressure setting. Attach the High Pressure Foam nozzle or select the foam setting on the 3 in 1 nozzle. If the detergent is too dense, dilute it with water. If you're using a high-pressure hose extension, fit the original hose.
