| Finish spotting |
Use acidic cleaners or abrasive tools. |
Use pH-neutral cleaning + wipe-dry protocol. |
Approve housekeeping chemicals; rinse residue; avoid bleach dwell; verify finish is dried after cleaning in humid rooms. |
| LEDs not working |
Assume electrical fault first. |
Verify flow threshold and turbine path. |
Confirm minimum flow; clean inlet screen; descale internal pathways where hard-water deposits exist. |
| Flicker |
Ignore pressure swings. |
Stabilize flow/pressure before part swaps. |
Check building demand variation; verify upstream restrictions; retest at stable pressure; clean debris that interrupts turbine rotation. |
| Weak spray |
Remove restrictor without documenting. |
Clean/restore flow path then evaluate. |
Descale spray face; clean screens; confirm stops open; then validate coverage and user comfort. |
| Leaks |
Over-tighten and scratch/damage finish. |
Seal properly and protect finish during install. |
Use soft jaw protection; verify sealing; ensure alignment; leak test before returning room to service. |
| Uneven pattern |
Wait until flow is severely blocked. |
Hard-water PM schedule. |
Set descaling interval based on water hardness; log per floor/wing for predictability. |
| Color/indicator confusion |
Use LED as temperature control. |
Commission mixing valve; treat LED as indicator. |
Verify actual delivered temperature; set limit stops; align indicator expectations with safety practices. |
| Inconsistent guest experience |
Mix models across rooms randomly. |
Standardize by property and room class. |
Choose consistent spray class + finish; keep spare parts; document PM steps for housekeeping and engineering teams. |
