PRESSURE WASHER TROUBLE SHOOTER
       Tech Tips and Troubleshooting
 for HOT WATER PRESSURE WASHERS

       Listed below is the problem you selected with causes, solutions and discussion

These instructions are intentionally basic.  We provide this information hoping they will assist you to get  your hot water machine going.  Servicing a hot water pressure washer can be very dangerous if you don't know what you are doing.  If you are not trained beyond these basic procedures seek professional help.  

Malfunctioning electrodes

Check electrode operation

First, a warning!  Electrodes are there to set the fuel on fire when it is being blown into the burner chamber at high pressure.  Just the description of the function should spark (pardon the pun) some caution, if not downright fear.

If you have no experience at this go to a service center to get the work done.  If you have some experience, try these basic instructions.  There is no information here, beyond the basics.  These instructions are intended to assist the owner of the machine, not professionals.  Professionals don't need to read this. They know what to do.

Why so cautious?  First, there is fuel being spayed at high pressure which is intended to be ignited into a flame.  Second, there is a transformer which produces thousand of volts of electricity. Third, there is an electrical spark being produced by the high voltage, which fires the fuel. Fourth, there is a very intense fire burning in a restricted area.

Beyond checking if the igniters are working or positioned properly there is not much we want to tell you about.  If the igniters are in good shape (not broken, burned or cracked) and after setting the igniter position and gap, according to manufacturers specifications, there is still no spark, then the problem is generally in the transformer.  Testing a transformer requires knowledge and the right testing equipment.  Don't touch the contacts to see if there is power there!  Go see a service guy.   

 

SOME OF THESE OPERATIONS CAN BE EXTREMELY DANGEROUS.  IF YOU DO NOT HAVE SUFFICIENT TRAINING IN THESE PROCEDURES, WE RECOMMEND YOU SEEK ASSISTANCE FROM
