Start with the sequence
For this Grundfos Sololift macerator complaint, note whether any sound occurs after normal fixture use. Record the last normal stage and the first change. A short description of that sequence is more useful than a guessed part name.
What might explain it?
The unit does not start can involve power supply, activation sensing or a motor protection condition. Those are possible areas for assessment, not a confirmed diagnosis or a claim about a particular Grundfos Sololift model.
Compare the selected setting with the result you actually observed. Mention whether other functions on the same appliance still operate. Avoid repeated resets, bypassing locks or testing internal components.
The Grundfos Sololift identification matters
Record the exact model from an accessible label or existing paperwork. Do not open a waste-connected unit.
Identify the exact pumping unit and connected fixtures. Similar casings do not establish equal discharge arrangements or interchangeable components.
A display code only has meaning alongside the exact product and its documentation. Photograph the full message rather than looking up a similarly named model and assuming it uses the same code system.
Before a visit for this complaint
Mention the fixtures connected to the unit and whether any are backing up. Stop using fixtures if discharge is not clearing.
Give the full address postcode, not just Catford or SE6. Appointment availability, the repair approach, charges and any parts requirement are confirmed individually.
