See full text

A method of detecting a clogged or partially clogged wash arm in a warewash machine involves the steps of: monitoring a rotational speed of the wash arm during a washing step of aware cleaning cycle or operation; and comparing the monitored rotation speed to a set threshold speed and, if the monitored rotational speed falls below the set threshold speed, triggering an operator alert to advise the machine operator to check the wash arm. An advantageous sensor arrangement associated with a wash arm manifold is also provided.
