Repairs this series usually needs

  1. Component Failure / Service Required warning
  2. Water Level Error and Lime Scale Error
  3. Sensor Error and Over Temp. Error
  4. Internal Error 1 between the power and control modules
  5. Maintenance Required reminder

The G4 ThermoPro Twin is Wilbur Curtis’s twin brewer with the G4 digital control. Look for G4TP1 or G4TP15 on the data plate. The brewer separates messages into warnings, which let you keep brewing, and errors, which stop it.

That difference helps in a busy shop. A Lime Scale Warning or Low Water Flow Warning is a chance to schedule service before the brewer stops. An Over Temp. Error or Water Level Error needs the brewer switched off at once.

We descale, test the probes and valves and check the module link. For an older twin, we tell you plainly when a bigger repair is not worth it. Because a twin brewer serves two sides, tell us which side shows the message when you call.

FAQWilbur Curtis G4 ThermoPro Twin Coffee Brewers questions
What is the difference between a warning and an error?

A warning lets the brewer keep brewing but tells you something needs attention. An error stops brewing. Treat a warning as a prompt to schedule service soon.

Where is the model on a ThermoPro Twin?

The data plate shows it, usually starting with G4TP. Give us the exact model when you call so we confirm the voltage and parts before the visit.

Why did my twin brewer stop with Internal Error 1?

The link between the power module and the control module broke. We check the cable and connectors, then the modules. We give a written price before any repair.
