| Master Caution | AMBER | A non-critical but important issue has been detected in the EC140E, such as low fluid levels or sensor faults. | Review the cluster messages and address the caution before continuing heavy work. | |
| Check Engine (MIL) | AMBER | The EC140E's engine control system has logged a fault affecting emissions or performance. | Schedule a diagnostic check with a Volvo technician at the next opportunity. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe limits, risking severe engine damage in the EC140E. | Stop the engine immediately and check oil level and leaks before restarting. | |
| Battery / Charging | RED | The EC140E's alternator is not charging the battery, risking electrical shutdown. | Check the alternator belt and connections; avoid shutting down until resolved. | |
| Coolant Temperature | RED | The engine coolant temperature in the EC140E is excessively high, risking engine overheating. | Shut down the engine, inspect coolant level, and let the system cool before investigating further. | |
| Hydraulic System | AMBER | A fault or abnormal pressure is detected in the EC140E's hydraulic system, which may affect digging or lifting. | Inspect for leaks or listen for unusual noises, and contact service if the warning persists. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or temperature is outside recommended range for the EC140E. | Check hydraulic oil reservoir and top up if needed; monitor for leaks. | |
| Low Fuel | AMBER | The EC140E's fuel tank is nearing empty, risking engine shutdown during operation. | Refuel as soon as possible to avoid unplanned stops. | |
| DPF / Regeneration | AMBER | The Diesel Particulate Filter on the EC140E requires regeneration due to soot accumulation. | Allow or initiate a regeneration cycle as indicated in the operator's display. | |
| DEF / AdBlue | AMBER | DEF/AdBlue level is low in the EC140E, which may lead to reduced engine performance if not refilled. | Refill the DEF/AdBlue tank at the next break to maintain emissions compliance. | |
| Water in Fuel | AMBER | Water has been detected in the EC140E's fuel filter, risking injector or engine damage. | Drain the water separator promptly to prevent fuel system issues. | |
| Fuel Filter / Water Separator | AMBER | The EC140E's fuel filter is clogged or requires draining due to contamination. | Replace or service the fuel filter as soon as possible. | |
| Air Filter | AMBER | The engine air filter on the EC140E is restricted, affecting performance and fuel economy. | Inspect and clean or replace the air filter element. | |
| Brake System | RED | A fault has been detected in the EC140E's travel brake system, reducing safe stopping ability. | Cease travel operations and have the brakes inspected immediately. | |
| Parking Brake | AMBER | The EC140E's parking brake is engaged or not fully released. | Disengage the parking brake before moving the machine. | |
| Swing / Slew Lock | AMBER | The swing lock is active on the EC140E, preventing upper structure rotation. | Release the swing lock if rotation is required. | |
| Work Lights | BLUE | The EC140E's work lights are switched on for improved visibility. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The rotating beacon is activated for increased visibility of the EC140E on site. | No action needed unless beacon use is not required. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the EC140E's operating hours. | Arrange for service at the earliest convenience. | |
| Seat Belt | RED | The operator's seatbelt is not fastened while the EC140E is running. | Fasten the seatbelt before operating. | |
| Fasten Seat Belt | RED | The EC140E detects the seatbelt is unbuckled during operation. | Buckle up before continuing work. | |
| Reduced Power (Limp Mode) | AMBER | The EC140E has entered limp mode due to a detected fault, limiting engine output. | Complete current operation safely and contact service for diagnostics. | |
| Engine Oil Temperature | RED | Engine oil temperature is too high in the EC140E, risking engine wear or failure. | Shut down and allow the engine to cool before checking oil and cooling systems. | |
| Door Open | AMBER | The EC140E's cab door is open while the engine is running. | Close the door securely before moving or operating. |

Most Important Warning Lights
Engine Oil Pressure Warning
Common causes
- Low engine oil level
- Oil pump failure
- Blocked oil filter
What to do
For the EC140E, immediately stop the machine, check the oil level and refill if low; if the warning remains, contact a Volvo technician to inspect the lubrication system.
Coolant Temperature Warning
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
On the EC140E, shut down the engine, let it cool, then check coolant level and radiator condition; do not operate until the cause is resolved.
Brake System Warning
Common causes
- Brake fluid leak
- Worn brake pads
- Hydraulic brake fault
What to do
If the brake system warning activates on the EC140E, cease machine movement and have the brake system inspected and serviced immediately.
Battery / Charging Warning
Common causes
- Broken alternator belt
- Faulty alternator
- Loose battery connections
What to do
For the EC140E, inspect the alternator belt and battery terminals; if the issue persists, arrange for electrical system repair.
Hydraulic System Warning
Common causes
- Low hydraulic oil level
- Hydraulic leak
- Pump or valve malfunction
What to do
Check the EC140E's hydraulic oil reservoir and inspect for leaks; if unresolved, have a Volvo technician examine the hydraulic components.
Frequently Asked Questions
What should I do if the DPF regeneration light stays on?
Allow the EC140E to complete its regeneration cycle as prompted; if the light remains after cycling, consult your Volvo dealer.
Can I continue working with the master caution light on?
You may finish the current task, but investigate the cause as soon as possible to prevent escalation.
How often should I check hydraulic oil in the EC140E?
Check the hydraulic oil level daily before starting work for optimal performance and longevity.
What does it mean if the DEF/AdBlue light comes on?
It signals that the DEF/AdBlue tank is low; refill promptly to avoid engine derate.
Why does the seat belt warning sound even when I am buckled?
Inspect the seat belt switch and latch for debris or damage, as this can trigger a false warning in the EC140E.
Is it safe to move the EC140E with the swing lock engaged?
No, release the swing lock before rotating the upper structure to avoid mechanical damage.
