3. Troubleshooting
3.1 There is a decrease in water/detergent flow, or the flow has stopped.
Most instances where the DECI is not performing to expectations can be easily resolved by simple troubleshooting
procedures. Below is a list of issues that may arise during post-processing operations.
Step 1) Verify that there is sufficient water pressure being
provided to the facility.
Step 2) With the DECI turned on, check beneath the cabinet on the left-hand
side to the water pressure gauge and verify that there is sufficient analog
water pressure. A minimum of 20 psi is recommended.
Step 3) Check the Dosatron particle filter for buildup or blockages and clean
as necessary.
Step 4) Inspect the drain below the filter screen inside the DECI tank. Clear
away any buildup or blockages. See
Section 1.5.1 Filter Screen Maintenance
for information about accessing the filter.
3.2 The ALARM BUTTON is lit up and the DECI will not operate.
3.3 The DECI Controller touchscreen is not reacting properly.
3.4 Water or liquids are leaking inside of or around the DECI.
Please review
Section 1.6 Alarms and Warnings
of this User Manaul for an explanation of the various alarm
codes and the steps to clear them.
If the DECI controller touchscreen is not behaving typically, power the machine down, wait 20 seconds, then
power the DECI back up. This action reboots the computer system and should return the touchscreen to normal
operation. If this does not resolve the issue, contact
PostProcess
Support.
During manufacturing, all the DECI plumbing fixtures were affixed and sealed using construction grade materials.
If any of the plumbing connections, pipes, or tubes begin to leak, shut down the DECI and contact
PostProcess
Support for further instruction.
3.5 The internal passages of the part are not being fully cleaned.
If the internal passages of a particular printed part are not being fully cleaned during post processing, there are a
few steps that can be taken to improve the support removal process.
Step 1) It is important for the pressure sprays and detergents reach the areas that need cleaning. When it is a
tubular structure being processed, try facing the cavity (the end of the tube or pipe structure that needs to be
cleared out) towards the spray jets to get pressurized fluids into the space being cleaned.
Step 2) For the detergents and sprays to work properly the surface area to be cleaned must be accessible to the
liquids. To aid removal of support, it is beneficial to prep internal cavities and other areas with dense support build-
up. Consider removing large chunks of support by hand or penetrating internal cavities for detergent accessibility.
