Faulty Ignition System
One of the possible reasons why a pressure washer motor is hard to start when water is on it is a faulty ignition system. The ignition system is responsible for generating the spark that ignites the fuel-air mixture in the engine. If there is a problem with any component of the ignition system, such as the spark plug, ignition coil, or ignition switch, the engine may struggle to start.
If the spark plug is dirty or worn out, it may not generate a strong enough spark to ignite the fuel-air mixture. Cleaning or replacing the spark plug can help resolve this issue. Similarly, if the ignition coil is faulty, it may not produce sufficient voltage to create a spark. Replacing the ignition coil can solve the problem.
Another possible issue could be a faulty ignition switch. If the ignition switch is not working properly, it may not send the necessary electrical signals to the ignition system, resulting in difficulty starting the motor.
It is recommended to check the ignition system components for any signs of damage or wear. Cleaning, replacing, or repairing faulty ignition system components can often resolve the problem of a pressure washer motor being hard to start when water is on it.
