WAZER Suddenly Turns Off - High Water Level
WAZER is constantly monitoring the water level. If the water level gets too high at any point, a safety shutoff switch (high kill) will activate to prevent the Tank from overflowing. If you hear WAZER abruptly shut off, or if it powers down in the middle of a Cut, we suggest you do the following first:
Lower the water level in your Tank to about the Cut Bed height. You may achieve this by a quick drain
Clean the Drain Filters and check dump hose by referring to Maintenance > Maintenance Procedures > Cleaning the Drain Filters..
If the machine persistently showing “check drain filter and dump hose“ consistently, then it indicates a larger problem in your system. Follow the series of checks bellow to isolate what isn’t working as expected.
Check: Are the pumps that maintain the water level working? Remove the drain filter cover from the rear of the tank and verify the drain filters are clean. Then remove the front tank cover to expose the used abrasive collection grommet. Select Setup & Maintenance > Maintenance > Used Abr. Collect.
Root Cause: If both pumps are not working as expected then the waste water cannot be drained out as quickly as the input from the high pressure nozzle. WAZER internal timers will not be able to properly maintain the water level.
Corrective Action: Contact Support for help with replacing non functioning parts
Check: Is water in the tank not reaching the drain filters? Remove the drain Filter cover from the rear of the tank. Select Setup & Maintenance > Maintenance > Used Abr. Collect. Once the collection system is active, observe the water level near the drain pick up filters.
Root Cause: If it is significantly lower than the main tank water level, then the tank baffle is blocked with abrasive and water can’t make it to the drain filters.
Corrective Actions: The abrasive block will need to be cleaned out. the best way to do this is Maintenance > Maintenance Procedures > Full Tank Cleaning
Check: Is the WAZER capable of draining water? Remove the right side cover. Then do a quick drain, see Maintenance > Maintenance Procedures > Quick Drain. Observe the rate at which water drains out, if at all.
Root Cause I: Given all the checks up to this point if the water level isn’t going down then there is something blocking the flow.
Corrective Action I: Make sure there aren’t any blockages in your drain hose. or that your sediment tank isn’t too deep. The most likely cause is that the end of the drain hose has become buried in abrasive if using a secondary baffle system or bucket
Root Cause II: If the water drains well then the there is something wrong with your Dump Valve. If the dump valve stays shut during the cutting, the water level will rise quickly
Corrective Action II: Go to Setup & Maintenance > Maintenance > Peripheral Check > Dump Valve. If you hear a click then your valve works. If not clicking emitted, your dump valve is not working .Contact Support for help with replacing non functioning parts
Check: Is the middle Water Level Sensor used in water management functioning? Navigate to Setup & Maintenance > Maintenance > Input Output Check > Input > Water Level Sensor. After that, navigate to Setup & Maintenance > Maintenance > water level setup.
Root Cause: While the switch is a simple device it can still malfunction or the connector can get messed up. If it tells the controller water level is "low" while in fact it is high, the control logic will not engage the dump valve throughout the cut.
Corrective action: Check for the connection under "Input" check mode. Once the connection is verified , conduct a "water level setup". The high pressure nozzle and drain system works alternatively to achieve a water level the machine deems "optimum" . This resulting water level will tell if the middle float sensor is working correctly.

Check: Is the Drain filter completely below the water level? / Is the drain filter straight ?
Root Cause: If the Drain Filter ends up deformed or is installed at an angle part of it can stick up above the water level. This allows air to get into the pump as becomes easier to suck air in than water. Once this happens it completely throws off the water leveling routine.
Corrective Action: Straighten out the Filter and make sure it stays below the water level.
