Volvo CE EC160E Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system malfunction has been detected in the EC160E, such as engine, hydraulic, or brake failure. | Safely stop the excavator immediately and investigate the source of the fault via the display panel. | |
| Master Caution | AMBER | A non-critical fault or maintenance issue has been detected in the EC160E that may escalate if ignored. | Check the instrument cluster for details and schedule necessary inspections or repairs. | |
| Check Engine (MIL) | AMBER | The EC160E's engine management system has logged a fault, possibly affecting emissions or performance. | Review fault codes on the monitor and arrange for diagnostic evaluation if the light stays on. | |
| Engine Oil Pressure | RED | Engine oil pressure is dangerously low, risking severe engine damage on the EC160E. | Shut down the engine immediately and check oil level and condition before restarting. | |
| Battery / Charging | RED | The EC160E's alternator is not charging the battery, risking electrical system shutdown. | Inspect battery terminals and alternator belt; seek repairs before continuing work. | |
| Coolant Temperature | RED | Engine coolant temperature is excessively high, indicating possible overheating in the EC160E. | Stop the engine and allow cooling; check coolant level and radiator for blockages. | |
| Transmission Temp | AMBER | Transmission oil temperature is elevated, which could reduce component life on the EC160E. | Pause operation to let the transmission cool and inspect oil level and condition. | |
| Brake System | RED | A malfunction or pressure loss has occurred in the EC160E's service brake system. | Stop operation and inspect brake fluid and system components immediately. | |
| Parking Brake | RED | The EC160E's parking brake is engaged, locking the machine in place. | Release the parking brake before moving the excavator. | |
| DPF / Regeneration | AMBER | The diesel particulate filter is full and the EC160E requires a regeneration cycle. | Initiate or allow the regeneration process as instructed on the display. | |
| DEF / AdBlue | AMBER | DEF/AdBlue level is low, risking engine power reduction or shutdown on the EC160E. | Refill the DEF/AdBlue tank at the next opportunity to maintain emissions compliance. | |
| Water in Fuel | AMBER | Water contamination has been detected in the EC160E's fuel system, risking injector damage. | Drain the water separator promptly to prevent fuel system issues. | |
| Low Fuel | AMBER | The EC160E's fuel tank is nearing empty, risking unexpected engine shutdown. | Refuel the excavator soon to avoid interruptions. | |
| Hydraulic System | AMBER | A fault or pressure drop has been detected in the EC160E's hydraulic system. | Inspect hydraulic fluid level and check for leaks or abnormal noises. | |
| Reduced Power (Limp Mode) | AMBER | The EC160E has entered a reduced power mode to protect critical components. | Check for related warning messages and arrange service to restore normal operation. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or quality is below the recommended threshold for the EC160E. | Top up or replace hydraulic oil as needed and inspect for leaks. | |
| Engine Oil Temperature | AMBER | Engine oil is running hotter than normal in the EC160E, which could affect lubrication. | Pause operation to let the engine cool and check oil level and cooling system. | |
| Air Filter | AMBER | The EC160E's air filter is clogged, restricting airflow to the engine. | Inspect and clean or replace the air filter element. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is clogged or the water separator requires draining on the EC160E. | Replace the filter or drain water as indicated. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the EC160E's operating hours. | Perform maintenance as outlined in the operator's manual. | |
| Work Lights | BLUE | Work lights are currently switched on, improving visibility around the EC160E. | Switch off work lights when not needed to save battery power. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active, signaling the EC160E's presence to others on site. | Use the beacon in high-traffic or low-visibility conditions. | |
| Swing / Slew Lock | AMBER | The swing lock is engaged, preventing the EC160E's upper structure from rotating. | Disengage the swing lock before rotating the cab. | |
| Overload / Capacity | RED | The EC160E is lifting beyond its rated capacity, risking instability or damage. | Lower the load immediately and operate within specified limits. | |
| Low Oil Level | AMBER | Engine or hydraulic oil level on the EC160E is below minimum. | Check and top up the appropriate oil reservoir before resuming work. | |
| Door Open | AMBER | A cab or service door is not fully closed on the EC160E. | Secure all doors to ensure operator safety. | |
| High Exhaust Temp (HEST) | AMBER | The EC160E's exhaust temperature is elevated, often during DPF regeneration. | Keep clear of the exhaust outlet and allow the regeneration cycle to finish. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Oil level too low
- Oil pump malfunction
- Oil filter blockage
What to do
Immediately stop the EC160E, check the engine oil level and top up if needed; if the warning persists, inspect the oil pump and replace the oil filter.
Coolant Temperature
Common causes
- Coolant level low
- Radiator blockage
- Failed thermostat
What to do
Shut down the machine, let it cool, then check coolant level and inspect the radiator; replace the thermostat if overheating continues.
Overload / Capacity
Common causes
- Lifting beyond rated load
- Incorrect attachment use
- Unstable ground conditions
What to do
Lower the load immediately, verify the attachment is suitable, and reposition the EC160E on stable ground before lifting again.
Brake System
Common causes
- Brake fluid leak

Frequently Asked Questions
What should I do if the DPF regeneration light stays on in my EC160E?
Allow the regeneration process to complete by keeping the engine running at the recommended RPM; if the light remains on, consult the operator's manual or contact your Volvo dealer.
How often should I check hydraulic oil levels on the EC160E?
Hydraulic oil levels should be checked daily before starting work and topped up as needed to prevent system faults.
Can I keep operating if the DEF/AdBlue warning light is on?
You may continue for a limited time, but refill DEF/AdBlue as soon as possible to avoid power reduction or engine derate.
What does it mean if the swing lock light is on while trying to rotate the cab?
The swing lock is engaged, preventing rotation; disengage the lock before attempting to slew the upper structure.
Why does the service/hour meter light appear on my EC160E?
This light indicates that scheduled maintenance is due based on the machine's operating hours; follow the maintenance schedule to avoid breakdowns.
