Waterlase Express Low Memory Warning: What the Message Is Telling You

You are between patients, the screen shows "105 Low Memory or Resources," and you have no idea whether the problem is the tablet, the laser or your treatment presets. That uncertainty is normal, because the message is short and does not say which part of the system is running low.

The documented guidance is simple. BIOLASE identifies this warning as Error 105 (Low Memory or Resources) and recommends restarting the tablet and the laser, then seeking service assistance if the problem persists. This article explains what that means in plain English and what to do if a restart does not clear it. If you would rather skip ahead, you can contact our repair specialists for a free diagnostic evaluation.

What Does Low Memory or Resources Mean?

The wording is general. "Memory" or "resources" could refer to several things, including saved treatment presets, the tablet that runs the interface, or the system's internal electronics. The warning text does not say which one, and guessing is not useful.

What the documentation does tell you is how the message is classified. The warning is a resource-related alert, and the recommended response is a restart followed by service if it returns. It does not say a component has failed, and it should not be read that way. An undiagnosed warning is not proof of a failed part.

Resource warnings on any software-driven device can have more than one cause. A one-time warning after a long session is a different situation from a warning that appears every morning at startup. That is why the pattern matters more than the single message.

If you use other BIOLASE systems, the same logic applies. Our Biolase WaterLase and Epic repair team sees software and interface messages across the product line. For the broader picture of what we handle, see our dental laser repair services.

Will Restarting Clear the Warning?

Often it can, and a restart is the right first step because it is what BIOLASE recommends. It costs you a few minutes and rules out a temporary condition.

Follow your operator's manual for the exact shutdown and startup sequence, and keep the order consistent:

Finish or safely stop any treatment in progress.
Close out of the tablet interface and restart the tablet.
Power the laser down fully, wait a moment, then power it back up.
Reconnect or relaunch the interface as your manual directs.
Watch whether the warning returns, and note when it does.

If the warning is gone and stays gone through a full day of use, it was likely a one-time event. Keep a short note of the date and what the laser was doing, in case it comes back.

If the warning returns right after the restart, do not keep cycling power indefinitely. Repeated restarts can cost you chair time without telling you anything new.

Why Does the Warning Keep Coming Back?

A recurring warning means a restart is not addressing the cause. We cannot name that cause from the message alone, and neither can anyone else without testing the system.

Here is what is worth recording before you call:

When it appears. Is it at startup, mid-procedure, or after a certain preset is selected?
How often. Once a week, every day, or every restart?
What else changes. Do you also see slow screen response, frozen menus or lost settings?
What you already tried. Restart of the tablet only, laser only, or both.

This information helps a technician narrow the problem faster. It also keeps you from replacing something that was never the issue.

Don't guess, and don't take the system apart or order parts based on a forum post. A free diagnostic evaluation from professional dental laser repair technicians will tell you whether you are dealing with a software or tablet-side issue or something that needs hands-on service. Pricing is transparent before any repair begins.

If you are ready to send the unit in, you can print a free shipping label and start the process without waiting for a callback.

When Is Service Needed?

Service is the right call when the warning survives a proper restart of both the tablet and the laser, or when it keeps returning. That matches the BIOLASE recommendation and avoids unnecessary downtime from trial and error.

Get it looked at sooner if the warning comes with other symptoms, such as inconsistent behavior, interface lockups or settings that do not hold. Those are signs the system needs a closer look, even though none of them confirm a specific fault.

Think about the cost of waiting. Every day a laser sits idle or unreliable is lost chair time. Manufacturer repair often takes 3 to 4 weeks and may charge for the evaluation. At Repair.Dental, turnaround is typically 3 to 7 business days, with priority handling available for urgent repairs, and the diagnostic evaluation is free.

Repair is also usually the more economical path compared with replacement. A warning that has not been diagnosed is not a reason to start pricing a new laser. Costs depend on the issue, which is why the free diagnostic comes first.

Repair.Dental also services other laser brands, including AMD laser repair, Zolar laser repair, Solea laser repair, SIROLaser repair and Elexxion laser repair.

Frequently Asked Questions

Here are quick answers to the most common questions about this warning. For more, visit our repair FAQs.

What does BIOLASE Error 105 mean?
BIOLASE identifies it as a Low Memory or Resources warning. The recommended response is to restart the tablet and the laser, then seek service assistance if the problem persists.

Does the warning mean my laser is broken?
Not necessarily. The message alone does not identify a failed part, and an undiagnosed warning should not be treated as proof of internal damage. A diagnostic evaluation is how you find out.

Is the "memory" in the message my treatment presets?
The warning does not specify. It could relate to several parts of the system, which is why testing is more reliable than guessing.

Can I keep using the laser if the warning appears?
Follow your operator's manual and your own clinical judgment. If the warning keeps returning, it is better to have the system evaluated than to risk interruptions mid-procedure.

How long does repair usually take?
Typical turnaround is 3 to 7 business days, and priority handling is available for urgent repairs. If you want details specific to your system, see our page on Biolase laser repair.

Does the evaluation cost anything?
No. Diagnostics are free, and you get transparent pricing before repairs begin.
