Quick answer
E3 on an IFB dishwasher means the water is not reaching the required temperature. The heating element or temperature sensor may be faulty.
What E3 means
IFB dishwashers heat water to 50-70 degrees C depending on the selected program. The E3 error appears when the control board detects that the water temperature has not risen to the expected level within a set time — indicating a heating system fault.
Symptoms: dishes come out greasy or not properly clean (because cold water cannot dissolve grease effectively), the cycle takes much longer than normal, or the machine stops mid-cycle with E3 on the display.
How to fix it
- Check incoming water temperature. IFB dishwashers are designed for cold-water connection, but if the incoming water is extremely cold (below 10 degrees C during winter), the heater takes longer. Wait for the room to warm up or connect to a slightly warm water line if available.
- Reset the machine. Power off for 5 minutes, then restart. A temporary sensor glitch can cause a false E3.
- Run a diagnostic cycle. Some IFB models have a test mode — consult your manual.
- Check for limescale. In hard-water areas (common across India), limescale can coat the heating element, reducing its efficiency. Running an empty cycle with dishwasher cleaner or citric acid helps descale.
- Call IFB service. If E3 persists, the heating element or the NTC temperature sensor needs testing and likely replacement. This is a technician-level repair.
Do not attempt to access the heating element yourself. It is connected to mains voltage and located under the tub — a qualified IFB technician should handle it.
What does the E3 code mean?
E3 indicates the water heating system has failed to reach the target temperature. Either the heating element is faulty or the temperature sensor is giving incorrect readings.
Common causes
- Failed heating element (burned out or limescale-coated)
- Faulty NTC temperature sensor
- Limescale buildup reducing heater efficiency (hard water)
- Control board relay not sending power to the heater
- Extremely cold incoming water (winter)

How to fix the E3 error
Check incoming water
Very cold water in winter can slow heating. Try running during warmer times.
Reset
Power off for 5 minutes, restart. Clears temporary glitches.
Descale
Run an empty hot cycle with dishwasher cleaner or citric acid to remove limescale.
Call IFB service
Heating element or sensor replacement requires a technician.
Use dishwasher salt
Fill the salt compartment to keep the water softener active — prevents limescale.
Safety first: The heating element operates at mains voltage (230V). Never attempt to inspect or replace it yourself. Always call a qualified technician.
Part you may need: Heating element / NTC temperature sensor
In India, hard water is extremely common. Use IFB dishwasher salt and rinse aid to prevent limescale — this extends the heater lifespan significantly.
Frequently asked questions
Why are my dishes still greasy after washing?
If E3 is showing, the water is not hot enough to dissolve grease. Fix the heating issue and dishes will come out clean.
Can limescale cause E3?
Yes — thick limescale on the heater insulates it, so it cannot heat the water effectively. Regular descaling prevents this.
Is E3 expensive to fix?
Heating element replacement is moderate cost. Temperature sensor replacement is inexpensive. Get a quote from IFB service.
