Hi
Just moved into a rented flat. It's got a power shower (no pump) and worked fine for a few weeks. It's now developed a consistently swinging temperature, going from way too cold to way too hot in a cycle of about
30 seconds.I don't know where this problem could have come from, and assume it's an issue with the electronics of the shower, but is there anything I'm missing, or that could be easily fixed? It would be great to avoid hassling (and therefore being hassled) by my rental company.
TIA
