The Roca Victoria 20/20f is a great gas wall boiler. It has a characteristic compact design (with a built-in pump and expansion vessel), and features high performance, fuel efficiency, is lightweight, and has a high thermal capacity with DHW at a constant temperature (it comes in several different versions).
Additionally, something that we find interesting that you will learn about in this article is its clear error code system. In addition to learning about its effectiveness as a domestic heating appliance, it’s also important to learn about the Roca Victoria 20/20f boiler’s error codes.
You should always have these handy so that you can rectify problems as soon as possible and keep your boiler functioning well. Read this article if you’d like to learn more about the Roca Victoria 20/20f boiler’s error codes and the best solutions.
First step: Understanding Roca error codes
The Roca Victoria boiler’s control panel, which is close to the error light, usually has a series of figures in a horizontal or vertical position that display the various temperatures:
- 90 °C
- 80 °C
- 70 °C
- 60 °C
- 50 °C
- 40 °C
For the sake of design continuity, the same temperature codes are used as error codes. When there is an error code, the LED display will sometimes light up. Common Roca error codes are as follows: Error 40-50-60-70-90, Error 40-50-70-90, etc. The numbers are displayed in sequential order, from bottom to top, or from the lowest to the highest number.
When the boiler control panel displays an error code, you should consult the instruction manual to find out what kind of error the code is indicating, and what the possible solutions are. For instance, in a Roca Victoria 20/20f boiler, error codes 50 90 mean that the heating probe may be misplaced, broken, or have a short circuit, and it you will need to resolve these problems.
Error codes are often quite accurate. However, as every technician knows, they can also be complex. They are intended to be interpreted by qualified professionals who can decide what the best solutions are, if these are not outlined in the handbook.
In many cases, resetting or restarting the boiler is enough to solve the error code problem and the unit will then work perfectly again. However, as we will see later on, this is not always the case. Sometimes you will need to clean, service, maintain or even replace faulty parts with new ones.
Roca Victoria Boiler 20/20f: Error codes
Below is a loss of Roca Victoria 20/20f boiler error codes. These are the same as other Roca gas boiler codes, i.e. the codes are the same in Roca RS 20/20 boilers.
| CODE | ERROR | SOLUTION |
|---|---|---|
| 40-50-60-70-90 | The gas exhaust cylinder is open and has a flame | Check if this is the case, and reset the boiler |
| 40-50-60-90 | The gas exhaust cylinder is open and has a flame | Check if this is the case |
| 40-50-70-90 | The burner is off and the ignition timing is too short | Check if this is the case |
| 40-50-80-90 | The flue gas thermostat or pressure switch’s pressure is higher than 0 | Check if this is the case |
| 40-50-90 | There is not enough pressure in the heating circuit | Check if this is the case |
| 40-60-70-90 | Safety relay problem. The power on timing is too long. | Check if this is the case |
| 40-60-90 | The boiler’s reset safety circuit has a problem | Check if this is the case |
| 40-70-90 | There is a power failure in the solenoid valve | Check for gas problems and restart the boiler |
| 40-80-90 | Insuffucient gas level or an electrical fault has occured | Check for gas or electricity problems and restart the boiler |
| 40-90 | The DHW (domestic hot water) probe is interrupted, broken or short-circuited | Check if this is the case |
| 50-60-70-90 | The safety temperature cylinder is open and has a flame | Check the safety cylinder and flow switch, verify that there is no air in the circuit and restart the boiler |
| 50-60-90 | The safety temperature cylinder is open but doesn’t have a flame | Check the safety cylinder and flow switch, verify that there is no air in the circuit and restart the boiler |
| 50-70-90 | There are problems with the safety relay, which is not closing after a water demand | Check if this is the case |
| 50-90 | The hating probe may be interrupted, broken or short-circuited | Check if this is the case |
| 60-70-90 | Locking has occured | The solution is to check if there is gas supply and that the ignition spark is still there |
| 60-80-90 | The pressure switch or flue gas thermostat doesn’t have the correct pressure | Check if this is the case |
| 60-90 | Flame relay is faulty or stuck | Check if this is the case and repair if needed |
| 70-90 | The safety fuse is open | Check if this is the case |
| 80-90 | The safety fuse is open while the unit is operating | Check if this is the case and restart the boiler |
