I have a Kenwood RC320 which I bought thinking it was a slow cooker. It has a aluminium bowl liner rather than the usual ceramic one. Is it a Rice Cooker? It is quite large for a rice cooker! Also, there are only two settings, warm and cook. When it is on warm it is only warm on one side and slightly warm on the other. When it is on cook it boils rapidly and quickly, possibly even too hot. (it is a 900w). Is it possibly faulty do you think? Hope you can help. Thanking you , Katy Burns
