ERROR: Check Drain Filters and Dump Hose
WAZER indirectly measures the rate at which water is drained. This Error exists to alert you when there is something preventing clear drain flow. It is most likely that the Drain Filters are clogging. To check this locate the Drain Filters which are located in the rear of the WAZER tank, underneath the Rear Tank Cover. To clean the filters refer to Maintenance > Maintenance Procedures > Cleaning the Drain Filter.
If you have recently cleaned your Drain Filters, but you are still seeing this error, it may be indicative of a larger problem. the following will walk you through debugging the problem.
Check: Is the Water Drain hose clear, have no obstructions, kinks, or sharp turns.
Root Cause: Any thing that can cause a resistance to the outlet flow will throw off the timing of the water leveling system as it assumes a certain drain rate.
Corrective action: Make sure that water can freely flow from the drain hose by removing any kinks or obstructions in the drain line.
Check: Does the middle float switch work. Navigate to Setup & Maintenance > Maintenance > Input Output Check > Input > Water Level Sensor
Root Cause: While the switch is a simple device it can still malfunction or the connector can get messed up.
Corrective action: Please refer to this page for detailed instruction. Contact Wazer Support for a replacement
If you have been successfully cutting before then the problem most likely has to do with excessive abrasive in the back of the tank. Please check if the middle float sensor can freely goes up and down to the fully extend without and obstruction.
Check: Is the Tank Baffle Clear? Follow the guide Maintenance > Machine Procedure > Rear Baffle Quick Check
Root Cause: If the Baffle is clogged then it will cause the water level sensors to see a different water level then the tank is actually at.
Corrective Action: To clear the Baffle requires a Full Tank Cleaning
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.
Check: Is the WAZER drain setup completely free of any issues and it is still unable to complete a cut?
Root Cause: A combination of unique factors in setup can add up to cause performance issues which are not readily visible.
Corrective Action: Please refresh firmware and contact customer support.
Next Time
We find that this problem most often happens after a machine has sat idle for a long time with a decent amount of abrasive in it or near the end of very long cuts. To avoid this problem form happening in the future we recommend running a few tank cleaning cycles before your first cut after the WAZER has sat for a long time. Also, if you are about to run a long cut it is good to run a tank cleaning before hand as well.
