Mend Karcher 620M Power Washer Pressure

How can i fix my Karcher 620M Power washer?

After connecting and turning on the water supply, I push the button to turn on the power, the motor turns on and runs as long as i keep the button depressed, with a good pressure of water coming out of the lance. However when i release the button the electric motor turns off.

sounds like the lock down of the switch is broke, bypass the switch to prove it
