Unexpected Shutoff During Cutting

1

One of the most concerning things to experience with the WAZER is when your in the middle of a cut and the machine just seems to restart itself. Rest assured that this is likely due to a safety feature designed to protect you and your equipment! You may need to reach out to Support to resolve this issue but it most cases we can get you up and cutting quickly.

There are two likely causes of a unexpected shutoff; a component triggering the overcurrent protection in the power supply, or a clogged rear baffle causing the water level in the rear filter put to drop quicker than in the tank.

Overcurrent
The Power Supply used in the WAZER has overcurrent protection that will detect when a component is drawing too much current and will cut power to protect the electrical system. When the overcurrent protection is triggered it will result in the WAZER shutting down for a moment and turning itself back on.

The most likely component to cause an overcurrent is the Low Pressure Pumps. To test if this component is causing the shutoff you are experiencing, run the Used Abrasive Collection system from the maintenance menu. This will turn on the Low Pressure Pumps, if the machine shuts off then restarts then we have narrowed down the root cause of this shutoff. Please reach out to Support so we can help resolve this issue!

If the Used Abrasive Collection system does not result in a shutoff it may be one of the other components. Run through all of the output checks on the page below and see if any of them cause the WAZER to restart.

If you are able to identify an overcurrent please reach out to us at support@wazer.com so we can help!

Rear Baffle Clogged
The water level in the tank is critical and the Hi-Kill or Lo-Kill float switches make sure that the WAZER cannot cut if the water level is too low or too high. If the water level triggers either of these switches, the WAZER may either stay shutoff until the water level is adjusted or if your rear baffle is clogged it may turn itself back on after some time.

If the rear baffle between the tank and the rear filter pit becomes clogged with abrasive it will prevent water from freely flowing between these areas. When this occurs the water level in the rear filter pit (where water is drawn from) will drop quicker than intended and may drop low enough to trigger the Lo-Kill switch.

If the water level drops low enough to trigger the Lo-Kill switch the WAZER will shutoff without warning. After some time the water will be able to travel through the clogged baffle and fill up the rear filter pit, allowing the WAZER to turn back on.

To test if this is what is causing your unexpected shutoff, run the Used Abrasive Collection system for several minutes and observe the water level between these areas. See the page below for instructions on testing for this!

If you are able to identify that the rear baffle is clogged, please perform a full tank cleaning and make sure to focus on thoroughly cleaning the baffle wall.

Test Results/Determining Root Cause
The testing procedure for both of these potential causes is the same but the results will help to determine the exact root cause of an unexpected shutoff. If the WAZER shuts down immediately and the water level is equal in all parts of the tank, it is due to an Overcurrent. If the water level in the rear filter pit drops as the system runs and then shuts off with a low level in the filter pit, it is due to a clogged rear baffle.

I hope this helps to get you up and cutting quickly if you run into this problem but if you’re still scratching your head please feel free to reach out to us at support@wazer.com so we can help!

I do have the issue where the power restarted during a cut, if I try to do the abrasive test, it also restarts.
If it’s over pulling power, how do I fix this ?

Also now with all the issues it says to check water sensors and back flow?
How and where do I check back flow ?

It sounds like your Low Pressure Pumps are causing an overcurrent, this could be due to the pumps themselves deteriorating or some kind of clog in the Low Pressure system. You should first try flushing the system to remove any clogs and if that doesn’t work the next thing is to clean the pumps out.

To confirm my understanding are you running a Pro WAZER or a Desktop WAZER? Did you update the firmware recently? The Backflow Sensor is only built into the Pro WAZER so it sounds like you may have the incorrect firmware installed on your machine!

It seems like there are a couple things going on with your WAZER so please reach out to us at support@wazer.com so we can help to troubleshoot these issues!

This machine has 7 hours of run time on it so deteriorating areas would be concerning if that’s the case.
It’s is a Pro.
The firmware was updated last week to 2.30, then was cutting for 3 hours when this restart happened.
I was only able to get back to it last night for my shift and I updated the firmware to 2.32.
Issues still persisted.

I only got the black flow and water level message when I attempted to just run a cut.

I had emptied the water in the bed, filled it, there is barley an abrasive in the filters, the back drain filters are spotless, no abrasive line clog, no water leaks.

How exactly to I flush the system? There is nothing in the manual book for this? Let alone cleaning out the pumps on a machine only used for 7 hours.

It’s hard as well since this machine I run at a second job, in the evening, 1/2 days a week and support is closed then.

If I do all the checks, the checks work except the lp pump YET if I do a water level sensor test the LP pump works.
It’s very confusing.

Hi Greg - I am now back at the machine and my only day this week.
I Have done abrsive flow checks, nozzle checks, drain clog checks, water level sensor checks and this machine still shuts off.

If i attempt a tank cleaning - you cant hit cancel or start since no buttons glow.
If i try to do an used abr. collect - the machine restarts
if i try to do an LP pump check - the machine restarts but if i do a nozzle purge (and did this 5 times) the pump comes on and all valves are in the green.

I am not back at this machine until next week, in the evening when outside of the support working hours.

I dont know what else to do, check, clean when i have done every forum and video i can find.

as an update of cleaning more areas for 2 hours and manually emptying the tank (again only 7 hrs run time on this) if i attempt a tank clean it constantly says check water level sensor (which are good and did multiple water level sensor tests) and checking the backflow drawn which i do hold the button up and have clear flow - there is absolutley no change in what is happening with this machine. And if i cant get to this error screen to check things, again it restarts.
Still cant even do a LP test.
we are now on week 3 of this machine being down.

@DuckieDee
I had a really random thought. Have you checked the magnets in the door? If those are too far away from the edges, it gives absolutely no warning, and will shut off the most arbitrary things. One doesn’t allow the machine to turn on, but one just shuts off the pump or something. It’s beyond frustrating that those things move so easily. I would hate for it to be something so simple, but maybe it’s just simple enough to be the issue.

Next time I am in, I will definitely take a look. Though I’m not sure where the magnets are to be honest.

@DuckieDee That one’s an easy fix. Look at the rubber gasket on the door you lift up, inside that is a small square magnet. Just take an allen wrench or something metal and scoot the magnet closer to the edge of the gasket. I just wish there was some alarm that states “door lock not engaged” or something along those lines so we can know that’s the issue. I was panicking one day when the pump wouldn’t turn on. I thought I broke the damn thing.
