Why does my Simoniz S1800 detergent not work?

  Brandon MooreAug 14, 2025
  Several factors could prevent the detergent from working correctly. The detergent container might be empty, so you should add more detergent. The detergent bottle or suction tube may not be properly connected; ensure these connections are secure. The detergent might be too thick and require dilution. A clogged filter on the detergent suction tube can also be the cause; try running warm water through it to remove any build-up. The detergent suction tube could be damaged or clogged, requiring you to remove the obstruction or replace the tube. Also, ensure the nozzle is in the low-pressure position. Finally, the discharge nozzle could be obstructed; in this case, blow out or remove debris with a fine needle.

  If the motor won't start, first ensure the On/Off switch is in the “ON” ( | ) position and the power cord is properly plugged in. Check the extension cord; if it’s too long, not the proper gauge, or damaged, replace it with a 25’ (7.6 m) or a 50’ (15 m) 14 AWG cord. Try a different electrical outlet to rule out inadequate power supply. Also, make sure that the pressure washer circuit breaker is not tripped. If it is, allow it to cool, and then restart the unit.

Why does the Simoniz Pressure Washer output pressure vary high and low?

  Inconsistent output pressure can result from several issues. The discharge nozzle might be obstructed; clear it by blowing it out or removing debris with a fine needle. The gun, hose, or power nozzle might be calcified; run distilled vinegar through the detergent tank to address this. Insufficient inlet water supply could be the cause; ensure the water is fully on and check the garden hose for kinks, leaks, or blockages. The pump might be sucking air; check that hoses and fittings are airtight and purge the pump by squeezing the trigger gun until a steady flow of water emerges through the nozzle. Lastly, the water inlet filter might be clogged; remove the filter and rinse it with warm water.
