  Kevin HardySep 2, 2025
  If your HydraMaster Vacuum Cleaner runs rough at high speed, remove and inspect the spark plugs, cleaning or replacing them as necessary. Inspect the spark plug wires and connectors for damage or loose connections, repairing or replacing them as needed. Check if the fuel pump is mounted in a vertical position near the fuel source, correcting it if necessary. Check for blockage in the filter, repairing or replacing as necessary. If operating altitudes have changed, contact your distributor to have the engine carburetor jets checked.

  If your HydraMaster Vacuum Cleaner system won't prime, inspect the check valves in the chemical pump, cleaning or replacing them as necessary. Check the chemical pump diaphragm, replacing it if needed. Inspect the check valve in the high-pressure pump, cleaning or replacing it. Inspect and clean the filter on the feed line in the chemical jug. Inspect and repair any loose, pinched, or damaged feed lines from the chemical jug. Inspect the chemical selector valve for leaks between ports and replace if necessary.

Why isn't my HydraMaster GTXR+ Vacuum Cleaner pump reaching normal cleaning pressure?
- A
  Amy RollinsAug 31, 2025
  If the pump on your HydraMaster Vacuum Cleaner isn't reaching normal cleaning pressure, start by inspecting the pressure adjusting valve, repairing or replacing it if necessary. Test the pump output volume directly from the pump at normal running rpm; if it's below the manufacturer’s specifications, replace the seals and inspect for defective valves. Check for a loose pump belt and adjust or replace it as needed. Check the engine rpm and adjust as necessary to 3,200 rpm under no vacuum load. Remove and inspect the primary orifice, tightening or replacing it if necessary. Inspect the primary and secondary orifices and reverse if necessary. Measure the primary orifice size and replace as necessary; the correct size is 0.021”.

  If your HydraMaster Vacuum Cleaner won't reach its normal operating RPM, inspect the throttle linkage for broken or loose parts, repairing or replacing as necessary. Check and clean the recovery tank filters to reduce excessive load on the engine. Inspect the recovery tank to blower hose, repairing or replacing it if necessary. Inspect the heat exchanger for blockages, cleaning or replacing it as needed to address excessive back pressure on the engine exhaust. Inspect the air filter and replace it if dirty.

What to do if my HydraMaster Vacuum Cleaner turns over but won't start and there is no spark?
- J
  James GarciaAug 29, 2025
  If your HydraMaster Vacuum Cleaner turns over but will not start, and there is no spark, first drain the recovery tank if it is full. Inspect the recovery tank float and repair or replace as necessary. Attach an inlet garden hose to fill the water box. If too many attempts are made to start the engine prior to filling the water box, it is possible to flood the engine. If these steps don't resolve the issue, consult a qualified service technician to inspect the engine ignition system.

Why does my HydraMaster Vacuum Cleaner turn over but not start when there is spark?
- J
  John GriffithAug 27, 2025
  If your HydraMaster Vacuum Cleaner turns over but won't start and there is spark, check if fuel is reaching the carburetor. Test for power to the fuel pump and inspect the fuel pump, replacing it if necessary. Inspect the fuel lines between the source and the carburetor, repairing or replacing them if needed. Test for power to the carburetor solenoid and inspect the solenoid, replacing it if necessary. If the engine is flooded, pull the throttle cable completely and crank until the engine starts. Inspect the spark plugs and replace them if necessary. If none of these steps solve the problem, consult a qualified service technician.

How to fix a HydraMaster GTXR+ Vacuum Cleaner that can't reach normal cleaning solution temperature?
- S
  Samuel BlakeAug 26, 2025
  If you're unable to reach the normal cleaning solution temperature in your HydraMaster Vacuum Cleaner, start by checking the temperature control knob and adjust it if necessary. A faulty dump solenoid could also be the culprit; inspect it and test its functionality. Excessive solution flow at the tool, often due to a jet that's too large or worn, might be the cause, so inspect and replace the jet if needed. Hard water scale buildup in the heat exchanger can also prevent proper heating, so descale the system. Lastly, inspect the interior of the heat exchanger for blockages on the exhaust side, removing any debris and cleaning as necessary.

Why does my HydraMaster Vacuum Cleaner truckmount overheat and shut down?
- A
  Anthony Mcintosh MDAug 22, 2025
  If your HydraMaster Vacuum Cleaner truckmount overheats and shuts down, the issue could stem from a few causes. First, the orifice or filter screen might be restricted, requiring you to remove and inspect it, cleaning as necessary. Another potential cause is a restricted or faulty dump solenoid. Inspect the solenoid and its hose, cleaning or replacing it if needed. Also, check the main fuse; if it's blown, inspect the electrical system for worn or shorted wires, repairing or replacing them. If the solenoid is operable, have a qualified technician test the temperature controller and sensor.
