The Bosch Tronic 3000T ES2.5 CA is a Canadian-market point-of-use electric mini-tank water heater. The matching Bosch manual identifies a 2.7-gallon actual tank capacity, a manual thermostat dial and an indicator lamp for heating operation. It is intended for local hot-water delivery near a sink rather than continuous whole-house tankless service. If water stays cold, observe whether other outlets have normal supply and whether the heater's indicator responds without opening the electrical cover. The reviewed installation and troubleshooting sections do not establish model-specific alphanumeric error codes. Stop use when a power connection is damaged, the tank leaks, or water is dangerously hot.
Bosch Tronic 3000T ES2.5 CA point-of-use mini-tank water heater ES2.5 CA Error Codes
No manufacturer-confirmed error symbols are currently recorded for this exact model. This does not prove that the appliance cannot display a code or warning.
No verified code list available. Use the matching model manual or manufacturer support for unexplained display messages.
The directory currently provides no verified error-code table for this model. Check the official model manual and symptom advice; do not apply generic codes from another appliance.
No hot water or slow recovery
First check that the heater has a safe electrical supply using the normal outlet or breaker access. Confirm that the thermostat knob is not at OFF, and allow the small storage volume to reheat after extended use. Bosch’s troubleshooting section describes both an unlit indicator and a heating-light-on/no-hot-water condition; neither establishes a particular failed component without diagnosis. If the lamp is lit but water stays cold after recovery time, qualified service may need to evaluate the heating element or a plumbing crossover.
Indicator lamp and thermal protection
The illuminated heating indicator is an operating signal, not a two-character error display. Bosch describes a high-limit safety switch and a reset operation in its manual, but reaching internal components involves an electrical and scalding hazard. This entry does not recommend homeowners remove the enclosure or press the internal reset. Have a qualified technician identify and correct the cause before restoring operation.
Leaks, pressure relief and water temperature
Check only visible external plumbing for drips, and keep clear of any water discharged by the temperature-and-pressure relief valve. Never cap or block the relief discharge. If a pressure-relief valve operates repeatedly, the tank leaks or water is excessively hot, switch off the heater and seek a qualified plumber or Bosch service. Protect nearby wiring from water and allow hot parts to cool before inspection.
Specifications and correct manual
Bosch lists this model in the Tronic 3000T 2.5/4/8 family at 2.7 gallons, 110/120 V and 1,440 W at 120 V in the model-family technical table. The unit has a manual temperature dial, not a verified fault-code display. This CA-suffix appliance is covered by Bosch's English/French Canadian-family manual dated February 2019; do not replace its instructions with the newer US ES2.5 edition unless Bosch confirms equivalence.
When to request service
- Heating indicator behaves abnormally, and accessible power and thermostat-setting checks do not resolve cold water.
- A thermal cutout operates again, the relief valve discharges, or the water temperature appears unsafe.
- There is a tank or electrical leak, or the appliance cannot be kept safely grounded.
