  Lauren LoganAug 18, 2025
  If your ThoroughClean Pressure Washer won't start, there are several things to check. First, ensure the power is plugged in and switched on at the outlet and the machine itself. Check the fuel level and refill if necessary, opening the fuel tank ball valve or fuel solenoid tap. Verify the water supply and inspect the float switch in the water tank. Also, make sure the Emergency-Stop, Battery Isolator, and Starter Isolator switches are disengaged. Check the pump oil level and top up with SAE15W40 or SAE30 if low. If the pump or boiler is overheated, allow it to cool down. Finally, if a timed by-pass shutdown occurred, switch the machine off and then on again.

What to do if my ThoroughClean Pressure Washer is running but not reaching the specified pressure?
- G
  Greg LangAug 20, 2025
  If your ThoroughClean Pressure Washer runs but doesn't reach the correct pressure, start by checking the suction for air leaks. Inspect and clean or replace any sticking valves. Examine the unloader valve seat for wear and either fit a BPV service kit or exchange the valve. Verify the water HP jet size and replace if it's the wrong size or worn out. Check the piston plunger H.P. seals and replace them if worn. Calibrate the pressure control valve if it's not set correctly. Confirm the motor revs and drive for low speed/rotation issues. Ensure there's sufficient water supply, cleaning filters in the suction line and increasing the supply hose size if needed.

Why is the pressure fluctuating in my ThoroughClean Pressure Washer?
- B
  Brittany LiuAug 23, 2025
  Fluctuating pressure in your ThoroughClean Pressure Washer can be caused by several factors. Worn or sticking valves can be a culprit; try removing, cleaning, and replacing them. Blockages or debris in the by-pass valve can also cause this issue, so remove, clean, and replace as needed. Additionally, ensure the pump isn't sucking air by sealing the suction. Finally, check that the jet size is correct and replace it if it's too small.

  Manuel AndersonAug 26, 2025
  A noisy pump in your ThoroughClean Pressure Washer can stem from several issues. First, identify and seal any air ingress causing cavitation. Check the gearbox or coupling for problems with the pump-motor connection. Inspect and replace broken or weak suction valve springs, and address any clogged or sticking valves. Examine and replace worn main crankshaft bearings if necessary. Also, ensure the inlet water temperature is not over 75 degrees Celsius; reduce it if it is.

What causes low PSI in my ThoroughClean D10M-36H after some use?
- T
  twhiteAug 27, 2025
  Low PSI in your ThoroughClean Pressure Washer after a period of use can be due to several reasons. It could be simple wear and tear, so start by checking and replacing the HP jet. Inspect and replace worn suction/delivery HP outlet valves. Replace the unloader valve or piston seals as required. Also, check for a cracked piston and replace it if necessary. Replace any failed or leaking "O" rings. Check and tighten the "Big End" if worn, and check and tighten drive belts if your unit is belt-driven.

What to do if my ThoroughClean Pressure Washer pump runs but produces no pressure?
- S
  sarahbauerAug 30, 2025
  If the pump in your ThoroughClean Pressure Washer runs but doesn't produce noise or pressure, first check if there is water in the suction line, as the pump may not be primed and is running dry. Then, ensure the gun is open and the nozzle is not blocked. Finally, check that the valves are not blocked.

Why is there excessive vibration in the HP delivery line of my ThoroughClean D10M-36H?
- M
  Martin JonesSep 1, 2025
  Excessive vibration or pulsations in the HP delivery line of your ThoroughClean Pressure Washer can be attributed to several issues. Start by checking and replacing the accumulator if it has failed. Replace worn wet end seals or plunger seals. Inspect and replace worn in/out pump valves. Clean or replace valves full of scale/dirt. Check and replace cracked pistons. Ensure there is an adequate water supply by increasing it if low. Finally, inspect and replace the gudgeon pin in the conrod if stretched.

What causes short plunger seal life in a ThoroughClean D10M-36H Pressure Washer?
- D
  Dennis DelgadoSep 3, 2025
  Short plunger seal life in your ThoroughClean Pressure Washer can be caused by cavitation or air in the system, so check the suction hose and increase its diameter for a bigger supply. Also, a damaged ceramic plunger can cause this, so replace the plunger if necessary. Finally, excessive pressure and/or temperature in the pumped water can be a factor; check the temperature and pressure of the inlet water.

Why is the oil in my ThoroughClean Pressure Washer pump emulsified or contaminated by water?
- G
  greenmercedesSep 6, 2025
  If the oil in your ThoroughClean Pressure Washer pump is emulsified or contaminated by water, it could be due to several reasons. Worn piston to crankcase oil seals can cause this, so check and replace them. Condensation from high ambient humidity can also lead to water in the oil, so replace the oil more frequently. Additionally, worn or cracked piston seals can be a factor; check and replace them. Finally, water blasted into the pump via the breather cap during cleaning can contaminate the oil, so exercise care during cleaning.

What leads to short bearing life in my ThoroughClean D10M-36H?
- K
  kimberlyquinnSep 8, 2025
  Short bearing life in your ThoroughClean Pressure Washer can be caused by problems with the pump-motor connection, so check the status of drive shaft keys, flexible coupling, or pulley. It can also result from the oil not being changed regularly, so change the oil as instructed in the maintenance schedule. Finally, excessive pressure of pumped water can contribute to this issue, so check the pressure.
