The Form Wash L can display several error messages to indicate that there is an issue with the solvent monitor. These include:

• Insert Solvent Monitor
• Solvent Monitor Error
• Solvent type listed as Unknown
• Unexpected Solvent Reading
• General Unexpected Error
• Temperature Out of Range
• The solvent temperature is too high
• Machine reporting that solvent is saturated with resin despite being new

To resolve most solvent monitor errors:

1. Update the firmware to the latest version.
2. Check the temperature of the solvent. If the temperature is below 15 °C (59 °F) for IPA or 18 °C (64.4 °F) for TPM, increase the temperature of the environment around the Form Wash L. If the temperature is above 29 °C (84.2 °F) for either solvent, reduce the temperature of the environment around the Form Wash L.
3. Check that the solvent monitor is submerged in the solvent.
4. Check that the solvent monitor cable is fully plugged into the Form Wash L.
5. Reselect the solvent type on the touchscreen. Check that the selected solvent matches the solvent in the Form Wash L.
6. If you cannot set your solvent type, drain a portion of the solvent out of the Form Wash L and replace it with higher-concentration solvent (e.g., 99% IPA). The solvent monitor determines solvent concentration by measuring the speed of sound through the liquid. If the solvent is too dilute, this measurement may fall outside of the monitor’s limits, preventing you from selecting a solvent.
7. Replace the solvent monitor.

If you see this error message repeatedly, contact Formlabs Support or an authorized reseller. Ensure the Form Wash L is connected to the internet to send diagnostic logs to Formlabs Support.

The Form Wash L displays the message An unknown error occurred if it encounters some other unspecified issue. Power cycle the machine by disconnecting and reconnecting the power.
