NT48/1 professional karcher not working. Changed fuse in the plug yet still not working. Replaced the filter. Still not working. Could be the motor not working?
Re: NT48/1 professional karcher not working. Changed fuse...
Is the motor running? If not, did you check the starting capacitor?
Did you check motor windings for continuity? Did the pump seize? Is electricity reaching the unit - wire ok?

It sounds like there may be a potential issue with the pressure build-up mechanism in your Karcher K2 compact. The constant motor running without water pressure could indicate a problem with the pump or the pressure switch. I would recommend checking the following:
1. Check the inlet filter: Ensure that the inlet filter is clean and free from any debris or blockages. A clogged filter can restrict water flow and affect pressure.
2. Inspect the nozzle: Make sure the nozzle is not obstructed or damaged. A blocked or damaged nozzle can restrict water flow and affect pressure as well.
3. Check the pressure switch: The pressure switch is responsible for regulating the motor and water flow. It's possible that the switch is faulty or not functioning correctly. Consider contacting Karcher customer support or a professional technician for assistance with checking and possibly replacing the pressure switch.
4. Examine the pump: There might be an issue with the pump itself. It could be worn out, clogged, or experiencing other internal problems. In such cases, it's best to reach out to Karcher customer support or a professional technician for further diagnosis and repair.
Remember to always follow safety precautions and consult the user manual provided by Karcher for specific troubleshooting steps and guidelines.
It sounds like you may be experiencing issues with the heating element on your Frigidaire window AC/Heater combo unit. Here are a few things you can try to troubleshoot the problem:
Check the thermostat: Make sure that the thermostat is set to "Heat" and that the temperature is set to a level high enough to activate the heating element.
Check the air filter: A dirty air filter can restrict airflow and prevent the heating element from functioning properly. Clean or replace the air filter if necessary.
Check the heating element: The heating element may be faulty and needs to be replaced. Consult the manufacturer's manual or contact the manufacturer's customer service for further assistance.
Check the blower motor: The blower motor may be malfunctioning and needs to be replaced by a professional technician.
Check the wiring: Check the wiring and connections, ensure that all the wiring is securely connected and that there is no damage to the wires.
Check the fuses: Make sure that all the fuses are working properly and that they are not blown or tripped.
Keep in mind that attempting to repair an AC/Heater unit can be dangerous if you are not familiar with the proper procedures and safety precautions. It's best to let a professional technician handle the repair.
If the problem persists, it's recommended to contact the manufacturer's customer service or a professional technician for further assistance. They can inspect the unit and determine the cause of the problem and provide a solution.

I doubt there's an internal fuse other than in the plug fitted if it has one. Karcher don't expect you to dismantle anything to get at a fuse but if you go online to the main Karcher website check out the parts list this may help identify anything. If it doesn't start and there's no humming noise like the motors struggling to turn then you need an appliance dealer or engineer to check the electrical side. Be careful what you do, water and electricity are a dangerous combination. Check the likely cost of professional help though, it may be more than a replacement washer?
you have an electrical short in the motor windings. you'll have to either replace the motor or buy another washer. also check to see if the motor isn't locked up with a piece of trash. to do that you'll have to dissassemble housing until you get to the motor. it should turn easily by hand. if so you have a short.
