  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?

  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?

  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.

What to do if my HydraMaster GTXR+ Vacuum Cleaner engine overheats?

  Several factors can cause your HydraMaster Vacuum Cleaner engine to overheat. Ensure proper ventilation by opening all van doors or installing a roof vent. Remove any obstructions that impede airflow around the truckmount. Check and replenish the oil level, as running the engine with low oil can cause severe damage. Verify that the engine RPM is correctly set to 3,200 under no vacuum load. Finally, inspect the heat exchanger for blockages and clean or replace it if necessary.
